Looks like there are some custom things being involved here, possibly with custom auth schemes and/or bad dynamic extension of auth schemes.
There were several imports from XenForo 1.2.0 into a XenForo 1.2.2 installation.

Several forums were merged with accounts being merged by email or username.

Next we are also using the XenCentral add-on, could it possibly be related to it?
Yes it does have an auth system, that last night I had forgotten to put the global salt into the config, so perhaps that was it, I put one in today and maybe it fixed it. Will wait and see if issues continue to occur.
