In what environment did the problem occur?

My multiplayer server that I was running

What went wrong? (Crash logs don't go here)

When casually playing, the console logs are spammed with the following:
[19:09:11] [Server thread/WARN]: Ignoring unknown attribute 'stepheightentityattribute:stepheight'
This seems to be causing lag, and killing all entities doesn't stop the error from happening... Is there a way of fixing this?

Did the problem cause the game to crash?

No.

Full crash report contents (if you experienced a crash)

The RAM issue should be solved with recent performance improvements. The spam, however, was caused by removing the step-height-entity-attribute mod or a mod that contained it. No idea the fix for that, but not a Pehkui issue.
