I just tried to recreate your setup but wasn’t able to reproduce your issue, lacking some info. Which engine is your game made with (RPG Maker 2000 or 2003, and potentially which patch(es) since I’ve seen that you were using them)? And which engine is detected for your game in the Player? (You should be able to see that in the easyrpg_log.txt file that the Player should have created in the folder of your game).
This must be some incorrect engine detection or that bug was fixed in the rpg_rt you are using.
You are currently using 0.8. can you get a continuous build from the bottom of the download page and provide the lines from easyrpg_log again? We added more info to the output which will help us figuring this out. Thanks.
My guess is that the version BetterAEP uses (2000 1.07) has the move picture bug fixed. We must improve our engine logic so that the bug is not simulated when this 2k version is used. (currently the bug is enabled for every engine older than Value!)
