3.9-SNAPSHOT:3825-c98139b,master
Bukkit 1.7.9-R0.1
No error message.

I've enabled the mechanic, and ladders simply don't fall.

Comment by me4502

They should fall on place, or physics update. Existing ones shouldn't fall due to lag reasons

Comment by xyZen

Yeah, they don't fall on place, or upon update. Wish I had more information for you.

Ah, I'm getting this error now:
