cave on the top row shows garble on subscreen

Just as an aside... is the "something something Drawn Under Caves" rule set? And does it do anything to the bug?

Please, provide a test quest.

Haha, I kind of hate the quest template provided with zquest, I have no idea about relational mode and stuff and as such, have no idea how to simply place a overworld cave combo somewhere.... it was very straight forward in 2.10 >.>

I don't see quite what you're getting at, or what has changed between 2.10 and now with regards to the act of placing a combo.

Well, maybe you could just tell me about the quest where you first found the bug.

Well in 2.10, you just scrolled down on the right to see a cave combo. In the newest beta, it is split into categories and I can't see the cave combo in the Badlands portion at the top. I can't find alot of tiles that where part of the overworld in 2.10 since they are mysteriously missing too.... (maybe there placed towards the end now or I have to manually find them in 'Quest -> Graphics -> Combo'?)

I can tell you the name, but you won't find it since it is a private beta. The issue also is not early in the quest, it is seen after level 4 or 5 is beaten. I can PM you the quest if you want.

The cave combos are 4, 5, 6 and 7.

Yes, do PM me the quest, but make sure it is unlocked and/or Link's starting position is near to the bug site.

Sigh....

Could someone else step up and confirm this?

I can't confirm this, it may have been due to video drivers or something. I tried various things in zquest and none showed the corruption.
