This build has various fixes and improvements to the baseline profiling system.
This includes some in-game notifications and indication to expect lag, as well as an option to prevent clients from connecting while a dedicated server is profiling.
Lots of performance improvements, so the lag should be very manageable now.

I’ve moved my downloads over to CurseForge. Existing downloads on my blog here will remain, but all future ones will be over on CurseForge. This will hopefully simplify things.


EDIT: I’ve pushed to fix a critical bug in generation. The Vanilla-Mystcraft mappings got flipped, so terrain was all wrong.

Check the Mystcraft Forums for updates and the change log.
