I tried it out on my megabase and found out that assemblers broke a lot. I do wonder does speed modules increase likelihood of breaking? I found it did not for some reason work on my Electric furnace mk 3 from Factorio extended plus. But fixing the rest I needed to set up was more than enough though I needed construction bots in every bot network and a few had them. Also it took so long time that assemblers no longer requested modules they had used.
This mod definitely keeps your bots busy! The default MTBF is 45 minutes, so for every 45 machines in your base, you can expect 1 to break every minute! This shouldn't be a huge deal as they're easy enough to fix and machines get automatically replaced.
I'll look into the replacements not requesting the modules they used. This is a bug!
Took a while to track down the problem. I misunderstood it as machines were properly requesting modules after breaking. It was unfulfilled item-request-proxies that weren't getting recreated. This is now fixed!
