yeah, i did the same

I tried loading my 1.0.0 creative map in 1.1.1.
All the mods required to play was updated.
First time loading it i got an error "bad allocation"
Then i rebooted my computer and second time loading the map i got this error:
...Data/Roaming/Factorio/temp/currently-playing/control.lua:9: attempt to ...

Why did the character menu got moved to the left?
There was no reason to move it
There is also no way to move it back to the old position.

also i had some mods enabled while joining a vanilla server and the mod sync box didnt appear.
then i tried disabling all the enabled mods and the game still crashed.

after a week of melting my brain, i finally come out with higher research density.
i thank quyxkh for his suggestion for 4-tile wide lane, and speed module on furnace. (i lost one week of my free time over this :cry: )

this factory has 462 spm and area = 162 * 132 = 21384 m^2
so the research ...

I cant upload the save file beacuse i was playing on a server.
The crash was very unexpected.

now this is more than epic

working, thanks
