I noticed that myself, but realized that it gave 1 "text box" per stat, even if you didn't gain anything in that stat. I you just keep pressing "X", you'll get through the levelup messages pretty quickly.
I know about pressing X, the problem comes in the end where the last message takes some time to disappear.
Edit - i cant believe only yesterday i noticed the extra spaces in the messages showing how much the stats increased, it's 3 extra spaces or something....
Edit 2 - i wished i could attach small files here: a male mage is refered as "her" by Nash, save state https://www105.zippyshare.com/v/JJHl3fHw/file.html
Edit 3 - When i got 10,000 in the red dragon cave the phrase "Got10000" was written, obviously a mistake.
Edit 4 - Not sure if it's a bug or it's something from the game, when playing the ocarina in the lyton's lake i can't hear the ocarina neither i can hear the singing of the singer.
Edit 5 - When fighting Royce if Jessica uses the "Cure Condition" to heal the ppl who got under "wraps" by Royce's spell she attacks Royce with a melee attack instead.
Edit 6 - I removed the healing ring from Alex but left the item in his inventory and even unequipped the ring still heals him.
Uploaded these files, i hope they help at least to fix edit 6 https://www.4shared.com/archive/cMQp6p9iiq/Lunar_-_save_games_-_save_stat.html
