Please make a stable 1.10.2 version, I'd like to have this mod as a dimension on my server. I've tried different profiles on both singleplayer and multiplayer, it always freezes or crashes on entering. I've even tried 1.11.2 with no other mods installed and it still crashed. I can generate the world on my 1.10.2 server but here's what happens when you try to enter:

Do you have the correct version of compatlayer?

I have 1.6, is that the correct one?

1.6 what? Can you give the full filename?

compatlayer-1.10-0.1.6

Why are you using such an old version? The last release is compatlayer-1.10-0.3.0.jar

This is most likely causing your problem

That's the version Forge said I need when I tried the mod for the first time so I never questioned it. It doesn't say anywhere in the mod description that you need this or what version, you could put that in so people don't have a problem like this anymore.

Downloaded the newest compatlayer and it works just fine, thanks for such a quick response and solution.
