Mod Version:
3.4.5.3
Forge Version:
Forge 1.11 - 13.19.1.2199

Description:
https://minecraft.curseforge.com/projects/dynamic-surroundings/files/2430134
This version is marked on CurseForge as 1.11 compatible, but in reality it asks for 1.11.2 and won't start.
Added later:
Found it is not compatible since 3.4.0.0

Hmmm....ok. Was wondering what it was going to break. Support for < 1.11.2 was "as is". Do you have a log of the issue - may be an easy tweak.

Just a bunch of warnings from FML, like:
Dangerous alternative prefix dsurround for name......
And this screenshot of what is actually happen when I try to install the mod:

Pushed v3.4.5.4 that contains a fix for this. Had to explicitly set a MC version so it would load.

Thanks!
