That's why I'm always focusing on the debuging before adding to much content. The difficulty is to see if the bugs are related to the game itself or the compability with other system. For exemple I don't have all the bugs links to the calls, I can only make asumptions based on the feedbacks.
Where are the old dialogue names? I though I replaced all of them.
Do not hesitate to provide example, that will help ;-)
Speaking from experience:
RPGMaker is an engine which tends to skip certain steps of execution for scripts & events if a player is holding the "Z" button or a designated skip / fast forward button.
The other aspect that can greatly contribute to this is if a player's device cannot properly or consistently run the game at a stable frame rate.
One can induce the sporadic instabilities for events by just holding "Z" for the fast forward effect.
A few ways to circumvent this:
1. Change event timings to prevent the skip and fast forward features from breaking the events.
2. Change how you implement waits and utilize pauses for certain functions to prevent skip & fast forward from breaking the "wait" function.
3. Disable fast forward for events that are sensitive to timings.
