When an expansions file (ypk) is added to the MDPro3 Expansions folder, if the content of the file has cards that modify those in the database (cards.cdb), these changes are not applied, which in the other clients that use this mechanism if it occurs (YGOMobile, KoishiPro PC, KoishiPro2 iOS); Generally what is placed in this folder has priority over the original files, so if a ypk is added that corrects a card effect, or simply updates its status since it officially became TCG so its Name and Description or Effect may change, changes do not apply. PS: it only happens with cards that try to modify those that already exist in the Database (cards.cdb) A practical example, this is a screenshot of the "test-update.cdb" file of the expansion pack "ygopro-super-pre.ypk", as you can see its cards are in Chinese, so if I open the game (I do use in Spanish) they should come out in Chinese, and it doesn't happen, if those cards have possible future changes for the correct functioning of the pre-released ones, and they do not load as they should, it means that there may be the possibility of errors occurring in the resolution of effects of the new pre-released ones.
