I've been running a "Enable All Planets Mods" supermod server for months now, with the goal of completing the entire tech tree (ambitious, I know). I recently noticed that Overclock Modules won't go in rocket silos or chemical plants anymore. Was there a recent change to Overclocks I'm missing? If not, I have to go poking around at all the other mods to find out what did what, but only this mod seems to be attached to Overclock Modules.

Figured it out. There's an option to index modules in the Voidcraft mod's Startup settings. That seems to fix it.
