Not going to lie, I'm not 100% sure what's going on exactly, but we're getting a server crash with lumberjacks. It might be an interaction with FTB Utilities chunk claiming? Here's the crash report: https://pastebin.com/Ncu5v6t9

AW2: 1.12.2-2.4.24

Okay, I personally experienced this crash in single player on .30 - when the lumberjack attempts to chop leaves, the game immediately crashes.

The fix for this was just released on CF. Also includes shared access to blocks and NPCs for all players in the same FTBU team.

Thank you!
