Hello,
I was updating some mods for one of my worlds in which I have been playing for a couple of days.
My previous setup was Modloader and Forge v107. I use a lot of addons but everything was tugging along.
I Thought that I would try out the latest release to check if it was just to ditch the ModLoader and carry on with my earlier saved world.
I am using MultiMC to help out with keeping setups separated which of course may affect the outcome. MC starts as it should, Everythings to be loaded., I load the save game and goes into "Saving Chunks". Log below.
I started to move around the order of jar mods being loaded (Rebuilding jar) at each change but no luck so far. Added removed AudioMod (since it was installed earlier...)
I can re-insert v107 and Modloader into the jar and the save game works once again.
I saw a post about missing leaves in some biome gen but here I don't even get to play.
I had OptiFine installed earlier but have since removed it to see if it had something to do with the bug.
It is not the "end of the world" since I can fall still fall back on v107 and Modloader, but I thought that I maybe should report the event, regardless.
I may only have made some rookie mistake but as for now I'm out of ideas of what could be wrong.
* Creating a new world also hangs directly after load but with some other function missing.
The current .jar files that are added are (and Load order)
Forge v120
4096 fix v. 4.2
Codechicken Core-Client 0.5.2 and
NEI Client 1.2.2.3
It does look as a "replacement" error in that the order should be incorrect in some way... but I don't have that many mods in the jar.
log file when creating a new world.
EDIT 1: Added info I do use "Multi MC's Rebuild .jar" before retrying if I change some .jar mod. (+ extra line about "replacement" error above)
