Minecraft crashing in 1.11

We just updated to 1.11 at Crit Cola, but the server is crashing when one of our players joins, and when another player opens a door using a redstone circuit. The crash below seems to be caused by an NPC, but I have no idea how to resolve this.

Can anyone help? Thank you!

This should be fixed in the latest SpongeVanilla.

Hey there. Thanks for the quick reply. :slight_smile: Has it been updated in the last couple hours? We’re running spongevanilla-1.11-6.0.0-BETA-0.jar, downloaded from this topic.

@Deamon just updated it, so try redownloading it now.

Thanks, guys! One of the affected users is not online to test, but the redstone trigger is no longer crashing the server. Considering this solved. Thanks again. You guys do great work!
