Hello! I'm running this in a pack alongside Cheese's Concentrated Solar mod. When the Solar Laser Tower leveled up, it caused this error:

The mod Quality Turrets Reworked (0.11.3) caused a non-recoverable error.
Please report this error to the mod author.

The mod Cheese's Concentrated Solar (0.5.1) caused a non-recoverable error.

Unsure which mod is more responsible in causing this, so I'm informing you both. Thanks!

It’s an issue caused by the other mod.
What I can do on my side is prevent non-vanilla turrets from being upgraded.
If you want, I can add this in the next version of the mod.

Thanks for the response, to both this and the other thread! I think that could be a good feature, though maybe instead of a checkbox, have it be a textbox where players can input a list of turrets to exclude? That way we can disable a specific one (like the laser tower) while leaving other modded turrets on? No sweat either way though. Thanks again!
