@Dj_Swagman , please avoid double posting, as it is against the forum rules. You can use the "Edit" function on your posts to add additional information you've forgotten or respond to multiple people. You can review our forum rules here. Thank you.
That is, posting after yourself when no one else has responded. You can quote more than one post at a time, just by selecting each quote before inserting them into the reply. In addition, you don't always need to quote people. If you feel you need to address individuals, you can use the @ and their username to tag them, as I've done here.
Yes, using it as an event can work, but it does help to understand how the tilesheets work. In this case, you would have wanted to put the wall and floor tiles in A5 and the objects into the B-E sheets. This would allow the objects to be allowed to be placed over non-autotiles.
