Found a bug when making blueprints after starting to research turret upgrades.
After each research the turret gets a new name after placing, the problem is that the blueprint uses that new name instead of the original "gun turret" name/id.
Using blueprint upgrader to upgrade the blueprint from gun turret to turrets mk2 for example fails.
Taking an upgraded turret back into inventory reverts it back to a standard turret which is added to the stack.
At this moment I'm pretty much clueless as I can't make a blueprint with turrets and that forces me to uninstall your mod so I can wall off my base.
Bummed out but hopefully you know of a work around as this is a pretty cool addon that tbh should be in stock (range upgrades) so thank you anyway! :)
