I think the Eclipse is still in Sola - it wouldn't make any sense to have it in the Tactics Mod because it never comes up unless you have Sola in your party.
Installing the new bits of the Tactics mod will automatically uninstall old components of the Sola mod, etc. But you can do it by hand if you really want to. :-)
I'm sure that I've managed to introduce at least a dozen new bugs by pulling the tactical components out of Sola, Ilyich, Valen and the Ritual and putting them into one Tactics mod. I would appreciate it if everyone would take a look and otherwise try things out.
By the way -- some nay-sayer thought that Solaufein was 90% tactics by weight. Removing all of the Tactical bits drops him from 700K to 530K. This demonstrates clearly that, as predicted, most of Solaufein is not fighting :-). If you're curious, most of the space in Solaufien is actually taken up by the lovely foreign language translations. :-)
The Tactics Mod itself is about 500K, which is an improvement over the Ritual (240K) + Ilyich (220K) + SolaufeinBits (unclear, but apparently aroudn 170K). This is mainly because you're not paying for multiple copies of WeiDU.
While I was restructuring I fixed a few things -- see the READMEs for details.
