Hi,

the recent changes of player -> character in 0.17.35 broke your mod.

Error while running event First_One_Is_Free::on_player_main_inventory_changed (ID 32)
real number expected got nil.
stack traceback:
First_One_Is_Free/control.lua:43: in function 'changeInventorySlots'
First_One_Is_Free/control.lua:17: in function <First_One_Is_Free/control.lua:13>
stack traceback:
[C]: in function 'get_inventory'
First_One_Is_Free/control.lua:43: in function 'changeInventorySlots'
First_One_Is_Free/control.lua:17: in function <First_One_Is_Free/control.lua:13

Changing line 43 in control.lua with defines.inventory.character_main fixed it.

Cu, steinio

Ya, I saw a comment on a different mod of mine earlier today and figured this one would be effected too. I saw in the forum they recommend just doing get_main_inventory() instead of using defines, so I'll fix it this evening.

Thanks for the bug report though.

Updated for the latest version.

Thank you.
