Mystcraft cart/portal bugs are fixed in Forge
I'm running what could be considered the ultimate pack on a server right now with only minor changes and no major crashes. I'm unsure if they could be waiting for official releases for things like RP2 perhaps?
As far as I know, the only pack waiting for full EE3 release is the FTB Map Pack. Ultimate pack was waiting primarily for worldgen (now done) and secondarily for stability and bugfixes.Is EE3 fully released? Last time I checked (several hours ago): no.
There's still an unfortunate interaction between MystCraft and RP2, what with the rampant marble generation issue on some mystcraft ages causing server failure.
This is a forge problem? What version fixes it? This bug destroyed my game and took me a bit of time to figure out how to restore it.
6.6.0.495
