when usinf painted glowstone in draw bridges when retracting the painted glowstone it will drop the item on the ground and also keep the items in the drawbridges inventory. Already told enderio devs about this and they are saying they can change nothing to fix this, this is on tinkers mechworks side.

I will take a look when I have little more free time, currently you can use the config to black list it.

Idea: is it possible to turn off tile drops in such a way that the drawbridge will do that for blocks in the blacklist? The major issues with those are that they still drop, but is this was turned off.....

Again, I'm not sure how possible that is.

yes i did use this config option to fix the issue for now.

Is this with all painted items, or just glowstone?

the painted glowstone is its own item but it can be changed to any solid block in the game. Just instead of it just being a regular block it now gives off light instead

I know that. I'm wondering if this happens with, say, painted fences.

I didn't know they existed but if they are handled the same way as the block, which it sounds like they do I would assume so

Since (EI)EIO does "special things" when painted blocks are broken, and CP wants to keep it like that, the only workaround is to make it so the blocks can't be placed at all. @Glassmaker, I'd add painted blocks to the default blacklist, unless @CrazyPants wants to do a PR to help fix this on TMech's side.
