That's a new bug to me... Are you playing the latest version. If so, back up any saves you have, delete the game, and redownload the game. It's possible there was an error when decompiling the game.
umm....actually, this bug happens with all of my other games that uses mv/vx, and i also played this game way before they decide to switch for newer engine. at first i thought it was just regular bugs but then i see them on other games like oba-san saga, Sword Princess Cistina (i think? i forgot since i decide to delete most of these rpg maker games anyway), etc. while older versions of both RA and milf control are fine.
other than installing various RTP and fonts from the game folder, i tried changing my region to japan, using local emulator with admin, tweaking windows font, runing on both x64 and x32 win 7, extract using winrar 5. nothing works.
regarding the "newness" of this bug, some people in this forum already mentioned it before

tbh i am a bit hesitant to post this question here and risk derailing this thread. but i don't know where else to ask this since i can't even find satisfying answer from google/official RM forum (the closest i get is to install unicode thingy, but i don't know which one is safe). if someone knows how to fix this, kindly reply it here, or better, use either one of these links instead:
