ok i can hold for as long as youd like but for every hour i hold your villager for you, itll be 2 extra tbt.
the hours only apply when im on tbt. so you already have an added up count of 8tbt earlier because last night, after the 10 hours of my message, i was on tbt for 4 hours before i went to sleep and you could pick her up once i woke up, however, everytime you hit 30tbt mark for the fee you have to pay up, this is to prevent people from making me hold villagers for an infinite amount of time and then cancelling later.
if you need more info. just shoot me a question and ill try to answer it
