In Goldenwood Forest after step 2 of the restoration process You can still move and go back on land though. EDIT: found another minor bug after completing step 3 of the Restoration Basically, after completing step 3, goldenwood forest becomes goldenwood park; however, if you enter goldenwood cave before triggering the event with team xen (when talking to Adrienn), when you leave, the area is back to goldenwood forest and you have to re-talk to Adrienn to get goldenwood park back (fortunately you don't have to gather the stuff all over again), so you get the cutscene once more.

Marianette, Angie and Ryland None of the mons in my team were fully evolved when I confronted Marianette so getting through her team was pretty difficult, especially her bulky Bewear I swept through Angie's team quite easily in V10 but the double battle it is now was hell and I had nothing to remove her field so I had to spam healing items on my Medicham with my second pokemon while he swept with high jump kick (I've lost count of how many times I lost because it missed lol, never trust a 90% accuracy) Had to use all the remaining revives I had to beat Ryland, and I really had an hard time beating his Claydol and Torterra because of how bulky they were (also it took me a while to understand why my Talonflame was powerless against Torterra xd)
