Yes, it also happens to me.

Yesterday, I've also noticed that once an AI gunner runs out of ammo with main auto-cannon, he doesn't switch to other weapons (i.e. MG). He just stands there, not shooting anymore. Also, I've not received any warning of "Out of ammo" from the gunner NPC.

Making possible to manually order an AI unit to change weapon would be, in my opinion, a short term fix. On the long run, AI should change weapon by itself whenever he runs out of ammo when you specifically and manually order them to fire at a certain target.

To OP : Would be better next time to report multiple issues on individual reports. 1 issue per report makes everything much clearer and void situations where devs needs to comment an issue as a "partial fix".

I'm not sure if it's related or it's another issue but I've noticed yesterday that once an AI gunner runs out of ammo with main auto-cannon, he doesn't switch to other weapons (i.e. MG). He just stands there, not shooting anymore. Also, I've not received any warning of "Out of ammo" from the gunner NPC.

I also have this problem. I have no other key mapped to E and the problem is still there. I have made a new profile, so maybe it's related? Other guys with this problem do you all have made a new profile or use the default one?

I get this too. Same OS.
