Hi, my upgrade blueprints don't work anymore when running your mod (I think it's yours - if not, sorry!). Even manually choosing a turret, setting quality and try to replace one doesn't work either (in map mode). When I place a blueprint and upgrading those, it works until the turret is actually build.
Tested with laser and flamethrower.

Thanks!

Edit: Deconstruction Blueprints aren't working either (only the plain one, which deconstruct all).

This is a side effect with hiding the turret variants and trying to make it look purely like a research upgrade instead of different turrets with larger range. Unfortunately, it doesn't play well with blueprints since you can select the actual turret variant. I'm working on a fix.
