Hi, I've had a bug reported on True-Nukes, but it seems to originate in RFW.
The bug report is here:
https://mods.factorio.com/mod/True-Nukes/discussion/627c50c7a5281c37ce7b8ff9
But can be replicated by starting a game with True-Nukes and RFW and hovering over the base game nuke.
The specs repeat forever off of the screen.
It seems to be an issue in data-final-fixes.lua, where the "rfw-fission-gfx" is set to something other than vanilla. To fix it you could just change the if statement in that file (I tested this briefly and it seemed to work) - you hide the setting when True-Nukes is enabled, so I imagine you intended to disable this code too.
