I'm not doing this to point fingers or to cause any unnecessary drama, but I'm doing performance tests with Frostfall right now that are intended to adapt to adverse Papyrus conditions. Unfortunately, my system is very clean, and my scripts iterate very fast without anything in their way. I need to put a roadblock in the middle that is going to really jam things up and then see how well it fares in my tests.
I'm not interested in reports of "Well I used XYZ that one time and then some random amount of time later it started giving me problems so I uninstalled it." I need something on the order of, "I installed X, did Y, and then everything went to hell in my Papyrus logs." Something very easily reproduced and is preferably well-known. Perhaps an old version of another mod that used to cause problems, but doesn't anymore since the author updated but the old version is still available.
Thanks!
Edit: And if you don't feel comfortable giving a mod name here in this thread, you can always PM me instead.
