I was trying to limit to 2 active tanks at the same time, but when buying tanks from the
STORE the tanks are generated in addition, 3, 5, 10 tanks, I posted this in the store plugin so that it adds a cvar to only allow you to buy the tanks above a limit, but anyway I believe this can be a fix for your plugin if you don't add this cvar in the
STORE, the only plugin I found to limit simultaneous tanks is this, and it seems that it doesn't hold the limit when a tank is spawned by the shop, thanks
