Alright, so I gave up on multiplayer support for this. ACS just doesn't want to work properly for me at all, plus I couldn't add all of the weapons in it. And given that I also can't do anything in it, it's best for me not to mess it up. I'll keep the dialogue shop for now.
If you can help me with ACS, make sure to contact me. But until then, don't expect any MP support for it. At this point, your best hope is to wait for the Zandronum team to fix the dialogues in multiplayer.
In other news, I started coding in the grenade launcher and the RPG, which should make battling tanks and helicopters easier. Hope you enjoy, Large hard 2019
