This is a suggestion, would it be possible to bring back the turrets as they were before the last turrets update?

There is nothing stopping you from using previous versions of this plugin. I do not know what you are referring to by "before the last turrets update."

you have to insert whateverf weapon you want + ammo required now in turret ( i think thats what hes talking about)

Yes, i ment the turrets to work as the old ones, no weapons require, no reload and only 1 type of turret
