As usual, the bug was rather stupid. Each chunk broadcasted the BlockChange packet even when it had no changed blocks. This caused a major CPU spike. Should be fixed now.
Great, does this also fix the eating and pickups issues?
No, but now there's a fix for that in the repo as well.
Just returned from best friends' wedding. What a day! Now everybody keeps telling me "now it's your turn"

Yeah, in a year, plenty of time.
Hahaha, did you catch the bouquet?
No, but our friends already know we're getting married in a year.
Is it just me, or is the forum web loading quite slow lately?
Yes I've noticed that too.
It seems to be loading fairly slow, but that could just be my connection.
