Weird passability problems

[Ludicus]

I've encountered some problems during playtesting my game.I could pass through some impassable tiles,albeit a limited number.I've checked the tileset in the database,not passable ( X ).Same with directional passability (4 dots).
The hero couldn't have been in "Through" mode,since he doesn't pass through all the impassible tiles.
This thing is very annoying!


What could be wrong?

You might be missing an impassable tile (or are using one that might look impassable but isn't), or you might be using a passible tile overtop of an impassable tile... Or, there might be something wrong with your tileset. Screenshot?

Uh,I'm using the RTP,and when I make a mistake(wrong placed tile) I delete it using one randomly-chosen blank tile(which are passable).Can that be the problem when deleting something second/third-layer?

(Here's what Blizzard's passability thingy shows)

You're always supposed to use the upper-left most blank tile for erasing.

Double thanks for the shorcut!

Actually, here's a good note for everybody: if you right-click on the map it automatically brings you back to the erase square (that's how you know)
