[jjdredd]

I got the same error and was wondering how did you manage to test with master_gold off in #931

[BielBdeLuna]

what do you mean?

[jjdredd]

How did you manage to test with master gold off in #931 when your game crashes with master gold off according to this issue?

[BielBdeLuna]

Because the crashes are apparently at random times, meaning that happen during gameplay and apparently unrelated to whatever the player is doing.

[jjdredd]

Strange, I get this crash all the time.

[BielBdeLuna]

I get this error whenever I load a specific save, in the kindergarden in prypiat:

maybe those ODE error messages "vector has zero size" influence the CKinematics::CLBone that fails?
