I've got a single meta variable with a string value that should always be 0 or 1 being stored on pages. I can set it using a simple dropdown box in a metabox and it seems to work great. For some bizarre reason, it sometimes gets changed from 1 to 0 seemingly randomly. I have no clue why, and it seems to happen even on a page I wasn't editing or updating. I'm baffled and don't even know where to begin looking because I haven't figured out how to replicate the problem.
Does anyone have any suggestions to search for a possible way to replicate this or figure out the cause?
