As mentioned in this other post https://forum.muhro.eu/d/3679-5-min-guyak-pudding .

Would be nice for buff consumibles (foods and potions) to not expire when on city. I can't think of any use for them out of testing DPS, whic you do on Main Office, a map where both consus AND bubblegum/manuals keep consuming, so it would just add the possibility of taking a break of those 30min.
