Error while running event upcycler::on_tick (ID 0)
upcycler/scripts/tick-handler.lua:87: attempt to index local 'struct' (a nil value)

Receiving this after I load my certain autosave, nothing fancy here, bottom to top: iron plate belt row, row of blue inserters, row of upcyclers ~9, output belt, row of upcyclers, belt row, happens every time I load the save

60x game speed

can you send me your save?

yes, where to? in any case, I really wish you would make the other awesome sink mod configurable with e.g. amount of slots for upgrade modules, or make rate configurable, as it feels much less cheaty and logistic/mechanics are very good, also not as bulky as this one

on my modding discord, also i can look into making the module slot count of the awesome sink configurable, or i might just increase it to 4 by default / as maximum

if you have upgradeable quality on that mightr be what is doing it

hmm?

i got the same error and when i disabled upgradeable quality (another mod) it worked

if any of you have propper reproduction steps do reach out
