This has been a longtime issue and I thought it worth bringing up again since the VE challenge to use a flamethrower is made harder by it.
A pervious update made it no longer possible to destroy friendly rally points and this was great. Unfortunately it was not also applied to ammo crates so you often see people either intentionally or accidentally destroying ammo crates because the button to get ammo is a single press but a double press orders your ai to destroy it. This is incredibly frustrating if you are using particular weapons that are very ammo hungry and you built your own crates to keep them running.
an example of this issue i ran into earlier today was a “friendly” who likely didnt understand getting ammo only needed a single button press and was constantly destroying my ammo boxes by double pressing on them every single time he switched mags.
If only ammo crates were not able to be destroyed by “friendlies” i wouldnt have to rebuild them 8+ times for one single obj zone.
