I found after latest update that few random passive provider chest on my map changed their status to be out of roboport reach even if they are and were before on required distance. Screen provided.
Chests have buged blinking status but they still works as normal - they still provide content and robots pick up items from them.
Factorio works as normal. But after I switch chest to standard stell chest (by manualy pleceing new chest over broken one) or remove broken chest manualy (by holding RMB) game becomes "corrupted" but works as normal till I try to save.
Game crash after save atempt, exactly after choseing and confirming the file (on saveing progres screen). This works also when game tryies to autosave (then it crash when saveing progres is shown) If I dont change anything with chests (don replace them or dont remove them), save works.
I found 8 such broken chestes on my map. Chests broke with not known reason, it just happened somewhere betwen 28-29 hour of game.
I tryied to repeat this proces many times, game crash every time with no eceptions. Even if I remove one such chest or all of them.
Crashed game can be closed only by task manager.
