Great. About to test that, but one more data point...
I just changed my M script to TR.TOG 5 (with the Ansible in Teletype mode) while using the rest of the Jumpy Edges script (no TO code in there... that was the only line in the M script). It crashed within ten seconds.
EDIT: As an aside, here's my thought as to what is potentially happening. It seems that the Teletype is internally stable. I was smacking it pretty hard with the Varigate while the M script was flipping one of the main toggles. Everytime I do anything involving the ii bus on the M script while using the main TT script triggers it seems to crash.
I think there may be some weird race condition involved with the M, ii, and trigger sampling schedulers, but only when using all three.
With my "No Triggers" test (M script triggering an ii message every 50 ms), things were stable.
With my "Lots of Triggers" test (M script triggering internal message every 50 ms), things were stable.
As soon as I have triggers, M, and ii together, that's when it seems to crash.
