Some Changes Not Saved Under XenForo
When making changes to existing data in certain DMs, the changes are not actually saved when the page refreshes.
I have only encountered this when modifying integrations, but this can occur with any DM that uses ::_isset to determine certain errors. Under XenForo ::_isset doesn't return true for values that were specified but that have not changed since the last update. Other DMs that might be affected by this are subscriptions, prefixes, permissions, among others.
Fixed in the next release.
