Describe the Bug

root problem:
frequent crashing causing inability to play game without substantial changes to how I perform activity. Issue present in latest (12-13-2021 10AM CST) build of Flywheel, same issue as initial 18.0 release of flywheel, still un-patched.

cannot do the following without crash:
-pause the game

Mod incompatibility (those observed to quickly cause issue):
-Create Mod (operate mechanisms w/ too many moving parts)
-Journey Map (open map UI and wait too long, or do auto-map button, OR modify waypoints)
-Mahoutsukai (opening the mod manual object, ingame book)
-Alex's Mobs (opening the mod manual object, ingame book and wait too long)

all above incompatibilities and core game pause throw same error:

Reproduction Steps

1.pause game
2.receive crash

1b. open Journey maps and wait 10sec (alternatively select map chunks)
2b. receive crash

1c. open manual book for Alex's Mobs or for Mahotsukai
2c. receive crash

1d. operate create contraptions
2d. receive crash

Expected Result

not crashing. removal of Flywheel causes all issues to resolve (sans create issue as it requires loading of Flywheel)

Additional Context

No response

Can confirm the crash occurs with more than just the mods jambox mentioned

@jambox5 Solution is to type /flywheel backend off. It fixes the crash.

EDIT: Never mind, only a temp fix, still crashes after some time

Does this still happen with 0.4.2-rc?

Does this still happen with 0.4.2-rc?
here's result of using 0.4.2-rc

12-16 EDIT:
after looking into the debug it appears the issue of .4.2-rc was related to seamless_loading_Screens mod, removal allows System to start normally. Original bug is resolved in all original scenarios, great work!

please close
