I seem to have a problem with the generation in my modish world.
I'm quite fond of mods that change the generation of the Minecraft world and add a lot of structure to that feeling of adventure and change.
So I use mods like Biome Bundle Nether EX the midnight OTG or biome's O plenty.
I have solid RAM on my side and the crash report clearly shows that the problem is not a lack of power, but rather a problem in entity generation and spawning.
Since this is beyond my ability to understand crash reports I'm coming to you, if anyone has a solution I'm willing to listen to find out where it comes from, so thanks in advance;)
I put below the crash report:
BTW I'm in 1.12.2.
