Strange. What heap replacement mode were you using? I've been running OSR for ages with mode 5 and OBSE without trouble. Faregyl 2.0 saw the late stages of its development using OBSE 0019b and never gave me that sort of problem.
It's a wild shot in the dark, but an issue that did come up during testing. Have you tried using the ABomb counter reset on one of the old saves? Near the end of testing, several nasty animation problems took root which were wiped clean when I reset the counter. The strange part is that it fixed it for every character I have, not just the one I reset the counter on. I don't see why it would help in your case, but anything is worth a shot, yes? Reset it even if it's not near 100% because in my case it only showed 37% but the problem is gone now and has stayed gone since.
And for the record, OSR has been behaving nicely with OBSE 0020 as well.
You should also be sure you've updated your Faregyl+Anequina patch as that does need to be updated to properly support Faregyl 2.0.

I am using the settings you recommended a while back, which as I've mentioned generally result in hours of stable playing without a sign of issues:
Heap = {
_comment = Heap replacement can produce MAJOR improvements in performance on Oblivion, only moderate improvements on Fallout
_comment = It crashes instantly on Fallout, is moderately buggy on Oblivion
_comment = Algorithms: 1=FastMM4 (requires external dll), 2=Microsoft (slow on XP), 3=SimpleHeap1, 5=ThreadHeap2
iHeapAlgorithm = 5
bEnableProfiling = 0
iHeapSize = 1024
bEnableMessages = 0
}
This behavior occurs even with a brand new game - with Abomb at 0%. I tried repairing it anyway but no difference in behavior.
Yes, I'm running the latest version of your patch for Elsweyr and Faregyl.
Given that I had this same behavior with Ivellon I'm really thinking this has something to do with some kind of hidden resource limit within OSR that's getting tripped when loading the cosave. Unfortunately the log file OBSE is generating isn't particularly descriptive at what is causing the crash, other than it's clear it's happening when the cosave is being loaded.
