UE4.6 Crashes ~5 seconds after opening project - corrupted?

Why is there no subforum for engine problems?

Anyway, using UE 4.6.0.

I get this error and sometimes the error after when I open my project. Day = ruined. The engine crashes after leaking 2.5+GB ram. Only thing I noticed when it opened and re-opened my previous windows is that a break struct node was no longer connected. UE4 would be fantastic if it had more stability than a one legged spider. It was saved / closed cleanly prior to this happening but the increasing memory usage from leaks over the course of 30-60 mins doesn’t go unnoticed. Using blueprints only, no code.

How do I fix it?

Edit: It could very possibly pertain to my anim instance. If I run the game as I open it before the crash, the character is stuck in TPose. The anim instance is not doing anything fancy and was not changed recently. The disconnected break struct node was also in the anim instance.

Decided to play with 4.7 for a break, but converting a copy to 4.7 then re-compiling everything fixed it.

Still would like a sub-forum for engine specific issues that don’t belong in these ones, or at least a Misc.

Hello,
Those kind of thread have more chance to be answered by opening them in epic feedback section. As it is solved, i don’t move it but if you could post to the answerhub at http://answers.unrealengine.com (same login than here) so we can better assist you. Epic staff will have a chance to fix it.Thank you!
