After fighting with Steam to no avail, the M&T v3.0 / EUIV v1.33.3 compatible TOT is uploaded as a new asset, that you can find here:

Really hope the creator updates this mod

@PikaPilot If you want something different from vanilla I suggest Ad Lucem M&T Submod which can be found in the Paradox M&T sub-forums under a threat titled "V3.0 Sub-mod Collection". I'm using the dark version and while It's not as good as Theatrum, It's still significantly better than Vanilla.

update pls~~~~~~~~~~

Any updates in the works?

Still broken for the new version of M&T.

Dark map & no optional files? Guess I'll play the vanilla map for now.

@Rhewlif, yes, i saw... investingating the matter.

@drphilmynuts, will check about those optional files, as i haven't worked on that aspecT.

Optional files are missing and since the latest M&T update the map appears very dark.

Yeah optional files are missing. I prefer the water to be blue.

I am also unable to find the optional files, besides the border files included with MEIOU.

The options files seem to be missing...
