Yes, there is that error, which we are working on. However, I am able to run the mission without issue with that error popping. I've also gotten the crash running this with normal, vanilla units that do not produce the unsupported uniform error. The crash only occurs when I hit the save button and then preview. In my mind, the crash is related to saving the map file, possibly with my extra class (cfgScenario), or with cfgFunctions. I should note, this has started occurring only with the last stable branch update.

Thank you for looking into it!

This issue appears to be resolved as of ver. 1.38.128937
Please mark the ticket as such.

Further information: Saving the file while it is open in the editor precludes every crash.

I've been dealing with this now for a couple hours. It is occurring every other time I load the mission.

re: cancerouspete
That fixed the F button changing firing mode, but when I hit ctrl-F to adjust stance, it changes firing mode again. Still will not adjust stance.

Ctrl-F has another default binding that was interfering. Not a bug.

Ctrl-F is default bound to suggest fire mode for your gunner in a helo. For some reason this causes infantry to change their firing mode as well. Closing issue.
