I searched and I looked at the last few days of posts and didn't see anything related, so here it goes.

 

Recently I updated my mod pack from build 933 to 946, and I started getting these errors.  I upgraded to 949 tonight to see if it solved the issue (it doesn't).  The crash happens whenever you look at blocks that apply use the fakeplayer code (it's happened so far to Bibliocraft Armor stands (example in the log) and Tinkerer's Construct Drawbridges, which makes me think it may be a Forge issue).  So far the crash has happened to both myself and one of my players.  Anyways, for the logs and crash-reports:

Update again, seems to have been fixed

949 is the last build, fake player is still broken. Downgrade to forge 9.11.1.944 temporarily

Humm hes using FakePlayer in a odd way, namely rendering. I'll have to look into it later, but not sure if I actually wanna fix this one. The FakePlayers were more designed for performing actions in world as a player not rendering them. {Breaking blocks and the like}

Drawbridges (Tinkerer's Construct) also crashes, and I don't think it use FakePlayer to render anything...do you want me to collect a crash report from that too?  The crash report was essentially the same, only instead of Bibliocraft classes listed, it listed TConstruct classes.

I know what the issue is, Im just curious of why it's creating fake players on the CLIENT.... I'll wait till the actual modders bring this up.
