Again, I have crashed solo, in hostile areas, not hostile area, and around other people.

Using shapeshift, polymorph, wildshape and shifter shape works correctly every time.

Epic elemental and legendary animal causes CTD most of the time. Both are the only epic feats.
Prefect. I will come up with a couple different class builds that use it to test as well in the meantime.

Has staff that wasnt able to replicate the crash been around people who cause mass crashes? Sometimes only certain people crash consistently which often points to different systems (windows versions, OSs entirely). It can have an effect.

I thought I was onto something but, not.

I thought maybe it was the Forest Walker boots conflicting somehow, but after I relogged, I shifted. There seems to be no rhyme or reason to the crashes.

I had NO problems a few months ago. Now I have constant issues. A peripheral change has to be the issue with the conflicting code.

Do you know exactly when it first started happening? That can help with trying to understand the origin of it.

If I am just wearing my normal equipment I will crash.

When I removed and re equiped my stuff piece by piece I didn't crash until I had almost everything but boots and belt on... then after that it didn't matter, I still crashed.

The earliest report I can find on it is from July, 26th.

Hey everyone!

If you have experienced this Epic Elemental Shape crashes on your druid or Shifter, please post here what Operating System and graphics setup you have. It may help figure this out.

I can add what I'm using , but I don't have the bug , still if that somehow helps narrow it down .
Using windows 10 , a really old AMD graphics card whos name is lost to time .
Also using GoG version of game with newest client extender .

Dae's speculated that it might be a shifter-only problem. I haven't gotten around to retrying my tests as a shifter, though.

I crashed during testing of it a lot. Though I'm curious as to how specs/OS should affect it.

I'm on a windows 11 insider edition. On an i-9 16 core processor with 32gb of ram, a GTX 3090, Nvidia, Dual SSD drives, 1 250 GB, 1 1 TB and a backup 1TB HDD

It's not shifter only , I crashed folks on my druid by going regular elemental (not even epic) , but never myself .

Hey guys, just started working on this issue past few days.

Important: If anyone has a reliable way to trigger this or notices any patterns or can even rule out anything please let me know!

I cannot reproduce it on my hardware. I've shifted hundreds of times with pure druid and druid/shifter both on live and on a test server off live.

In examining a crash dump from a player who crashed with this bug only a few things I can tell,

1. It appears to happen shortly after some direct X calls.

2. Appears to then crash addressing memory outside what is allocated to the client, in what I think is a __thiscall function where the ecx register has some garbage in it. It's doing a bunch of xmm register manipulation... I suspect trying to do some kind of game world matrix maths here. I don't know without doing extensive reverse engineering.

I postulate that if others are crashing due to this then some character data of the shifting player must be sent to other players which triggers a similar direct x and/or game world rendering math issue. So I'm going to try and focus my efforts on reversing what all the server sends when EffectPolymorph is called.

I examined the UTC (creature files) used for these summons and all four are part of the base game files and are not customized in any way. They ship with the game.

Hey, Dae! DM Feel Good and I are able to replicate the crash at will. The issue we replicating it is seems to be solo. For example. Him and I are in Mist Lake and he casts, first time cast, I crash. Second time cast, neither crash. Third time cast, he crashes. Fourth time cast, I crash.

This is only dependent on the fact we're in party together. Should we not be in party, then I am unaffected completely.

If you need more information, or testing on this. I am available to assist you in this endeavor.

I'm not sure I totally follow.

Does he crash by himself or require another player/party member?

And you think only other players in a party with the shifter would crash?
