Sorry for suggesting something: Couldn't be better to have a list of the addons that could cause trouble when using FSDT apps?
I don't have any crashes, and I keep installing stuff, but still haven't found a problem...
I don't want to think that a general statement like "several users found to be related with using lots of other 3rd party addons" will suggest a limit on the numbers of the addons we may use in our simulators, which is obviously a very unfortunate approach.
You are now confusing this with another ENTIRELY different issue, which doesn't have anything to do with what is being reported here, which is the StackHash_0a9e error in Couatl.exe (which of course I or anyone else at FSDT is able to replicate either), with the last user reporting instead a StackHash_0a9e error in Prepar3D.exe, so they are at least TWO different issues, possibly similar, although, if you search on Lockhed Martin forum for "StackHash_0a9e" related to Prepar3D.exe, you'll find many reports of it, none of them associated with any of our products, but it seems to happen for a number of reasons.
The one you are confusing with, is another problem of many "unrecognized id" in the error log, which MIGHT be caused, instead, by Simconnect flooded with commands by too many addons, so we don't get a chance to talk with it, or it replies with corrupted data. But it's NOT what is being discussed here.
We are obviously trying to understand what really causes BOTH problems but, you will understand that, as long as we are unable to replicate it, we can only rely on user's help because the only possible explanation is some kind of conflict with something we don't use or we don't know.
Unfortunately, while users seems very active posting here, even if I asked repeated times to have a Teamviewer connection, at least with those that have repeatable crashes, but nobody with either these two problems has contacted me back to arrange it.
Now, it's 2:20 AM here, and I'm still posting, and for EACH and EVERY crash report, I ALWAYS try to replicate the same situation as reported (compatible with the addons I have, of course) and as of today, I still haven't seen A SINGLE crash on my system. Same as anybody else at FSDT.
