did you by chance add that stack by console? if so then lona isn't programmed to grow any if thats the case it won't increase unless you add more stacks manually as for how long it takes to grow it takes upwards of a week per stage
nope, got it by rebirth
then wait some period of time if it still doesn't become 2 after like 1.5 weeks send us a save
ok i fixed that shit by updating game to 9.1.1.1.
now they do grow
thx for helping anyway
oh yeah i recall there was a bug before that version
