The land before collision

In a very low chance probably 2% there is a chance that a map i make doesnt work and the character can go through every collision, no matter what there is the character can walk throught it, ive seen the DB tileset and its fine but some maps just do that and i have to delete them(copy and paste tool wont work) can anyone help me on this? also i dont hold CTRL

I'll assume you are using XP...

Okay, hmmm... could you post an image of your DB on the tileset that is allowing you to pass over it?

Thats the problem, the DB is fine but he still goes throught everything.
but here it is.

And you changed nothing on that tileset or it's different functions? (passability/priority/direction pass/ect..)

Also, try to create a test project with a map made with that tileset. Does it still come up that error?

Finally, does it ALWAYS happen, or is it only sometimes? If it is only sometimes, tell us what events are on the map that this is happening on, because the database cannot be changed from inside the game (from what I know).

actually it happens rarely and it doesnt get events yet except the hero starting point to where i can see how the map turnes out. It's also with any tileset but in a rare occasion from over 175 maps ive made it's only happened 2 times, a house room and a volcano city.

The most common reason this happens is when the user erases a tile on the second or third layer with an invisible, but passable tile. Whenever erasing, you need to always use the blank tile in the UL corner. Try running over your maps with thatr
