I just checked the Mod I had downloaded of your Mods .
The Zip was labeled "FutaMod_121EXP , so, it should have worked, right .
Inside, on the "Mod_Info.txt" sheet, it stated "minimum-version": 1.33 .
So, guess it really wasn't even 1.21, and why it wouldn't work, in the Beta 1.3 version of the game .
That's the reason I was asking about a lower version, and before you say, "Just up-date to 1.4.4" . . . tried that , and for some strange reason, (even Madox doesn't understand it), it won't run on my PC at this time , so, I'm stuck with the Beta 1.3 .
Also, couldn't find a "Version 1.33" of the game, even though most of the "Mods" here are listed for that version, (oldest vers. before ver.1.4/1,4.1 became available). . and strange again, is that some marked as "ver, 1.33" work, while others, marked "ver.1.33" don't .
