Founded another, weird, bugs in v0.5.9.6: when MC are trying to deal with "Sins of Father" quest, choosing Tia + when fighting Umah/Ork Smasha.
First: If we`ll start to hold "skip text" button (LMB for me) in the moment before entering Madrag Kaz forest, where Tia will talk to Lyvia about Katherine, the some kind of "value table" start to mess with events: blue message about "eggs event" will pop up -> picture with sex will appear (rare chance to see Tia + Dasan sex scene), blocking part of screen without ability to remove (if you won`t restart and dodge a bug) -> sometimes MC will start to "fill up water into vial" from air, which will prevent sex picture.
Second: each time, when Umah or Ork Smasha (40+ lvl enemy) are trying to use Double Attack, the affinity info about girls will pop up in middle of fight.
