In this case the second room mana cost is
5 mana and 2 blue mana but it shows here as same cost as the first room. However when to pay the mana it is correct. Just have to be careful not to press to fast and end up with the incorrect room
#Second room mana price not correct

When you unlock this door, this Room deals 4 damage to target creature an opponent controls.
(You may cast either half. That door unlocks on the battlefield. As a sorcery, you may pay the mana cost of a locked door to unlock it.)

@wind cedar seems the details still see the rightsplit as leftsplit if it's room only, and even I use this drawManaCost(g, details.getManaCost(), x - padding, y, w + 2 * padding, h, manaSymbolSize); on cardrenderer, is there something not updated cor the cardstateview of room cards? the other split card works
nvm I'll just force to get the cost
