Hi there. I wanted to come and report two important bugs that both seem to do with cutscene skipping:
Final Shot Quest - Elemental Arrow Longa Dungeon
If you skip the cutscene using the cutscene-skipping XML, this dungeon will fail on the boss causing the character to be stuck and the mobs will not spawn. Basically the quest can't be cleared. I had to re-install my client to get this to work as not even disabling data-read from Abyss fixed the issue.
G18 Episode 1
I'm not as sure exactly what is going on here other than Tiara can cause the client to crash when starting up Episode 1 of G18. Once someone starts Episode 1, they will crash on the cutscene. If you try to log in, your character will immediately be placed in the cutscene again, which will result in a crash. This essentially means the character is unplayable until you do a fresh install again, which was the only way I was able to regain access to a character in this situation.
No, I do not data pack my mods, I only use the data reader from Abyss and disabled that in both of these situations to no avail; only a fresh client worked. I just think these are very important issues that can cause a lot of frustration especially for new players that definitely seem to have some correlation to the features in this mod.
