Just wondering if anyone has had any trouble converting their worlds to the new anvil format. I'm pretty sure I heard that there may be a few problems with it in worlds involving mods but since ic2 and similar mods were updated to 1.2.3 I haven't heard anything about it. So hopefully no news is good news?
I'm still waiting on a few more mods to update till I upgrade.
As long as the block IDs are the same it should be good.
Allegedly if there's anything on the 127'th layer in the old savefile, 1.2.3 crashes out.
1.2.4 fixes that. (allegedly)
