Okay
Version 4.1.5 will fix the issues related to the HEA gear (as you mentioned, the plates and the engine are already working properly). I’ll release it tomorrow.
For the containment structure, I think it’s better if it isn’t recyclable to avoid massive quality recycling of HEA plates.
But I might add a setting allowing players to change that.
For the base items (fusion stuffs and railguns) and the lithium battery, the quality mod is acting strangely, and I need to look into it further, so it will take longer to fix.
