The filenames of one or more of your mods suggests you got them from a repost site.
Please read up on the StopModReposts project (link in my signature) for info on why this is a bad thing.
I installed forge 28.0.18 for MC 1.14.4 but it doesn't show up in my launcher. It does show up in the versions folder.
reinstalled it many times but it didn't work.
also installed 28.0.17 and that didn't show up either.
forge for 1.12.2 does show up though.
I did read something about creating a new profile, but that didn't work either.
This is correct. I had a mod that adjusted biome temperature/rainfall over time (for seasonal variation) and there would be grass/leaf color discontinuities right along standard chunk boundaries where one side hadn't been re-rendered recently.
