In 18.37, shift-arrow moves items 2 squares, rather than 1 square. This doesn't happen infactorio 18.36. Not sure if this is a mod bug, or a game bug!

I'm getting the same thing here, 18.37 makes things move 2 tiles at a time.

Yes, this is not good. Please fix.

Same issue here.

I believe this is a result of the new on-grid blueprinting taking into account the 2-tile snapping of rails.

Came here to report the same bug, can confirm it's happening here also. Very frustrating!

I agree with @gnemonix, has to be something to do with the new blueprint grid snapping.

In control.lua, line 151:
--Distance to move the source, defaults to 1 + grid shift
local distance = event.distance or 1 + entity.prototype.building_grid_bit_shift
Change to:
--Distance to move the source, defaults to 1 + grid shift
local distance = event.distance or 1
Tested, works.

@Mig53: thats because Covid-19 is active. For safety reasons "local distance" is moving everyone further away.... ;-)
And thanks for the quickfix.

Indeed, it works! Thank you very much for that @MiG53.

+1, please fix it!

I noticed this too. Came here to report the issue. It's really annoying.

Fixed! I hope

yes, definitely fixed
thank you very much
