Confirmed - modified RscMapControl fixes this issue

@Geez, pretty please, this bug is kinda easy to fix, and mod creators don't want to keep crutches just to keep the map working

Hello 3Vaker and thank you for the report.
We are going to look into the issue internally.

Geez

I made a little demo mod, just in case it could help devs (and managers) to understand and fix it
M button will open custom menu.

Any updates on this issue after month passed, @Geez ?
Still hangs the game as of 1.02.150928, is it even accepted as an actual issue?
P.S. Is it ok to mention BI Staff using @?

Hello 3Vaker.

Never had this issue, even after 1.1, with DayZ Expansion Team, we were being able to create MapWidget without map in hands, the only issue we encounter, it was, you were not being able to put widget on top of map widget.

Well, you guys are doing a great stuff, but haven't published a thing yet, so I can't check your config files, but I'm 99.99999% sure that you have modified RscMapControl. Start the game with this thing loaded (without any of your mods):

And see if it hangs. And if it does, tell me what could possibly go wrong

Fixed in 1.04.(something)
