Hi Marc,
Sorry I didn't link the docs! What Yamamura linked to is correct (specifically the bottom paragraph).
Given that the block I'm using is a Feed Block, is it supposed to not always be in sync with the DB records it's showing due to the caching? If I change the field on a record, it will only update after a certain amount of time or if I go to System -> Clear System Caches. Interestingly enough however, another block that comes from a plugin the same exact template updates immediately (it's in the forum header and not the body, so not sure if that makes a difference).
Thanks!
