I went to do my daily IHDPC missions and after crafting 3 the mission disappeared and said "error: you cannot have this mission." The attached photos show the error message along with the 3x IHDPCs that were crafted. As noted, I was not a member of a group at the time. The daily IDHPC limit is 5. Not sure what happened there...

Additionally, I had an error with this mission the other day where even though I had all the required mats, the mission would not complete. I tried leaving the station and entering again but nothing worked. I did not think to take a picture of this at the time. I aborted the mission to try again, but it seems that that was the 5/5 daily missions and the mission disappeared. Is this an intended consequence of the daily limit or a bug?

The "Worst error message possible" award goes to Raybondo!

That error message only happens if the client and the server are not synced up correctly. the client thinks you can still take the mission but the server is saying your daily limit was already reached. The limit is 5 within a 24 hour period. The counter doesn't get reset at midnight. or whenever.

To try to resync the counters, try logging out and back in.
