i dont know lua to much but
base of what i could find this should be change to the bottom one due to api changes in 2.0 but i could be wrong
entity.surface.spill_item_stack(entity.position, { name = name, count = count }, false, entity.force, false)
\/
entity.surface.spill_item_stack{position = entity.position, stack = { name = name, count = count }, force = entity.force}

i will test it and to see if it works

alright i got it working had to also edit my save and replace control.lua in the save to with my edited version to

replace
"entity.surface.spill_item_stack(entity.position, { name = name, count = count }, false, entity.force, false) "
on Line 124 and Line 527 with
"entity.surface.spill_item_stack({position = entity.position, stack = { name = name, count = count }, force = entity.force})"
in control.lua

I made the changes you mentioned for line 527 with the code below , but now i get a new error that the itemID is not correct

527 : entity.surface.spill_item_stack({position = entity.position, stack = { name = name, count = count }, force = entity.force})
