Hello, I was not able to get Laser tower work and when investigating why I noticed that one of the mods I have - "Endgame Combat" - has research, which increases range of turrets. The issue is that it replaces turret entity with a new one for each new research range. So instead of "Solar Laser Tower", I have "Solar Laser Tower [Range Boost 6]". This seems to mess up detection of heliostat mirrors surrounding the tower, mirrors simply say there is no tower in range.
The solar power tower works just fine, so mods are not completely incompatible, but I am not sure if there is easy way to fix it.

Will investigate, thanks!

Doesn't look like I can do anything simple on my end, but reading Endgame Combat's GitHub it should be pretty easy for them to disable range upgrades on these turrets, I will raise an issue there.
