Hello Gedemon,
as you maybe read in my above posts I'm using the MPMPM tool to turn some of my mods to DLC format. I noticed two things, resp. bugs.
First, when you hover over the city banner you don't get the popup anymore that says "City "x" will produce "y" in "z" turns".
The second is that when a unit can be promoted, there is no information when hovering over the promote button whatsoever, it's just a blank popup.
I tried using the MP version of the mod you posted to see if it's a fault on my side and although the promotion popup works fine, the city production one does not. Could the two be related somehow or do you have any ideas what could cause those problems?
Thanks in advance for any help.
PS: The mods I combined for myself are
Christian Denominations (Historical Religions) (v 8)
City States Leaders II (v 7)
Great Prophet Historical Names (BNW or GK) (v 26)
Hindu Denominations (Historical Religions) (v 1)
Historical Religions (BNW or GK) (v 43)
Islamic Denominations (Historical Religions) (v 22)
R.E.D. Modpack (v 27)
PPS: In your MP version of the mod I noticed it's v28 and also now found it on github. Is that one still being tested or why isn't it available via download link here?
PPPS: I also have the problem with just using R.E.D. (v27) and IGE as modpack.
