Never seen this happen before:
Two projects called Mary and George (not their real names).
Finished Mary last month. Started George and finished it this month.
Took a look at the data in George and a bunch was missing. Couldn't find the data until looked at the Mary project and saw that her data got bigger and the date/time stamp changed.
Sure enough, data from George tried to save into Mary (but the surveys were different so all that saved was some administrative variables which were common to both).
Running on a network using Ci3 v2.6.16. SSIfield and .Ci3 files looked fine (pointed to the correct projects). The server was changed just prior to beginning George and there is some suspicion that that had something to do with it (e.g., permissions or some-such).
Question is has anyone ever encountered this or a similar issue and what was the resolution?
