Hi, I've been hosting a dedicated server and etc. hardly any modded files at all, not ones that would really mess up any of the game files, just modded weapons is all, but..
The Tank and Humvee drop calls are bugged, each time i try spawning a Humvee or a Tank it spawns a regular jeep instead.

Thank you for taking the time to look over this.

this was the case in the 0.91 version (the multiplayer session version). This is fixed in 0.92 though.

Only issue is, I still have this issue with my 0.92 server files, any suggestions such as re installing?

yes I don't think this would be a wrong idea anyway.

And what should I do in-case re installing doesn't fix my issue?

Hmm.. are you using the scripts included with the game build (media/packages/vanilla/scripts) or the (old) script zip provided in earlier than 0.92 dedicated server posts? This could explain it, if you're not using the scripts included with the game build.

Ah, ok that may explain it, i'll try messing around with it some time and see if it fixes anything.
