Crash on creating new world

[emeryplyler]

I was running a modpack where I had disabled some of the mods and added in EMI and MouseWheelie. Not expecting it to work, I tried to load an old singleplayer world from before I had removed a bunch of mods and got a nullpointer exception and then the game put me at the server selection. I then tried to create a new world and it got stuck. I scrolled up from the point in the log where I killed the process up to a place where it seems to be placing the strongholds in the new world. I used MultiMC.

If you need it, I will post the modlist from before and after I removed some. It's modified from Realistic Survival 1.2.

PS: I love your mod. Thank you for your time and your hard work :)

This is a crash from the mod Polymer. You should update it.

[emeryplyler]

I can't find it in the mods folder and none of the mods that embed it are in the mods folder either. Should I install it?

[emilyploszaj]

It's in your log so one of your mods has it installed. Installing a newer version manually will update it

[emeryplyler]

It was Universal Graves that installed it. Thank you!
