Error with loading the world?

[Iqew]

So I've been casually playing rimworld as always then I got 2 raids back to back on me. I was able to deal with one really well and the other with a dead colonist. I saved right before I took on the 2nd raid group so i decided to reload to the time before I lost the 1 colonist (She was my best doctor).

The problem is (you guessed it) it won't load. It loads up to 90% then it says there is an error and that I should check an error log. I don't know where the log is so i can't show you guys. I only know about crash logs.

Also, i run quite a few mods (about +-15 mods).

My previous saves won't even run as well. The autosaves 2 days before the raid. Yeah..... GONE
I'm a bit sad since this is a really good colony of mine on it's 2 in-game month.
