Several of spells you mentioned have id's greater than 9999. Anything over 9999 creates problems with eq titanium client and the custom spell file listed is based on default titanium spell file.
It sounds like you are likely using a SoF or eqlive spell file.
At first glance, I would say that your spells never worked and that even though they showed up on your end, they were not in the server's database!
However, I think this quick jump could be extremely wrong. In fact, it may all of these spells worked before the recent spell changes, so let me consider the other option:
The previous spell database actually supported through SoF or live. It may have come peq or some other location and sourced in. Then, since lillu, tyler, and I use eq titanium spells, it would have removed some of the previous spells.
In Summary:- You were using a SoF or later spell file and the spells never worked anyways OR
- THF used to support SoF spells but no longer do
Hope this clears up the possible issues! It would require lillu or tyler's comment to clarify which case. I have no clue what the highest spell id in the database used to be.
