I've added the EXP fix after v1.03, so the next update will have that. I also fixed the false positive in Falgar's Palace. Thanks for the bug reports!
For the optional scenes, I was unable to find 1 in Rok's Fort (I did find all 15 Masters and did the scene with Jason/Rod). I just started a 3rd run and will check again, along with the Treasure counter.
EDIT: Sorry, my error on Fort Langley and Stahl Dam, updated my comments above in case you saw an earlier comment. Additionally, on my 3rd run, the counter started at 2, and reduce by 1 after I did the scene with Jason/Rod (and I talked to both).
