Had 3 crashes recently, all on MP in the TTI server. Cant remember doing anything in particular, just flying around in the hornet or harrier. All 3 have an access violation in the crash file, not sure what this means, but here is the logs.
I have never experienced crashes like this prior to 2.5.4. dcs.log-20181227-151034.zip dcs.log-20181226-234110.zip dcs.log-20181226-183806.zip
