[translated]
In the mod settings there is an option "How many warps to advance to the next quality level". I thought it was the quality of the items. But it turns out, the quality of the enemies. I only found out about this when I opened the source file, which contains the non-existent option "Set when biters will gain quality upgrades". Apparently, you removed this option once, and now it is not clear what quality you are talking about.
