For those who obtained the lab key in wrong order causing to get stuck at Lysandre Labs B3F, or simply stuck due to flag errors:
FIX method:
1. Remove 4 key on items (Lab Key Card A, B, C, Elevator key) - set to value '0' and uncheck anything related
2. Go to 'Event Flags', uncheck 1 value under 'Event' tab - Index 29 - DD09A5AF5869E155
3. Uncheck 4 values under 'Field Items' tab

FF919DF7529EB402 - Lab Key Card B
FF919AF7529EAEE9 - Lab Key Card C

Then save and obtain in order! You can use go thru walls cheat but make sure u obtain in order to trigger the event.
