I too was having the same issue as above. I've unpacked and looked through so many wad files and the only other files i have downloaded with "NEO_MANA_COST_FUNCTIONS.LOL" is the "DATA_DLC_VXP.wad" so i removed it and repacked it. Your "NEO_KTK.wad" also has this .LOL file and i also removed and repacked. Worked a treat! I am now given the option of tapping creatures to pay for mana costs.
My next problem is with the
Obelisk of Urd. I'm not prompted to name a creature type when the card enters the battlefield. I get the following error in the log:
[lua] [string "Content\Functions\NEO_CHOOSE_TYPE_FUNCTIONS.LOL"]:103:
parameter mismatch or too few parameters [expected bzS32]
I've tried to look at it, but I am a n00b at coding anything so if you dont mind, could you have another look and see what could possibly be the problem?
Thanks for all the great work you've done thus far. It really is quite amazing!
