All you need is in that A3 crash.rar (Dxdiag, rpt, bidump...)

This happened during playing an official Arma III mission or were you running some custom MP mission/mod? if so, can you please add the mission/mod so we can reproduce your crash? Thank you

This happened without any mods and It was custom mission, I will attach it.
BTW It happened only once when I took mags from ammobox.
(Is it here ENG only? Can I write here Czech? :P)

EDIT: Mission is up. You simply try to take those caseless mags from ammobox (There are about 3 ammoboxs, you have to find out which has them, sorry). It happened after few restarts of mission.

Thanks, I'll check the mission you attached.
Please write only in english as not all Arma 3 devs are native czech speakers

Please delete Arma3AlphaProfile files ( there are 2, so both) in c:\Users\<User>\Documents\Arma 3 Alpha\ and try to reproduce the crash and let me know please

Sure!

I don't think this has something to do with the mission it's self. Same thing happend to me wenn i tryed to take a 6.5mm Silencer out of a custom Ammo Box in a mp mission i had setup my self. (no mods only bi attachments in the box, no mods in the entire game also)

Win 7 x64
Alpha 0.5.102571 normal build (not the developer build)

I don't know...I tried it 15x and game didn't crash. I don't really know maybe I was caused by something else there were five other players but I don't know what they were doing :(

this issue is not related to a concrete mission at all. Neither A3 profiles, or HW configuration. Main problem is in MP implementation of a new gear system which is still in progress(let's say >90% is done in SP and +-70% in MP). So beg my pardon for that and stay tuned with DEV distribution. We are working in 14days milestones and the next one I will be focused on gear MP

Thanks for info! (BTW Nice nick :D)

should be already fixed.. can someone confirm it?

I hadn't any crash so far
