I found what I believe to be a mod incompatibility.
Mod(s) : Education Mod
Why? After installing the Education Mod the rate of surgery failure went to 100% to every attempted operation, even with my level 16+ doctors. I tried this with just this mod, Core, CCL, and Education loaded [not in this order] to double check. Loaded up several different colonies and tried this several times with different levels and different operations, the result was always either minor or catastrophic failure. After removing Education Mod everything went back to normal. I hope this helps anyone having this same problem.
On a different note; I love this mod and I enjoy playing with it. Its totally worth any wait that might come with an update, as long as we eventually get to play with it again. Now, back to A13 and my lovely colony! Have a great day!
