I can place it, it works...but nothing picks it up. I tried drone deconstruction. I tried placing new floor over it. I even tried removing it with grenades. Nothing works. Once its placed, its placed.....

Hmm that's interesting, what version of the mod are you using?
And are you using other mods?
I've yet to run into any compatability issues with other mods.
Also I assume holding the same flooring in hand and holding right click to deconstruct doesn't let you either?

same here can't remove the tiles, i'm using a long modlist including a few large mods space exploration, krastorio, factorissimo2, got them all from the ingame mod manager, all up to date

Is it ALL the floorings or just a particular one?

I've only tried the power floor, I havent had need for the others. I can try it and let you know when I next log in.

A list of mods used would be helpful too.
I've played with SE and it worked fine but not some of the other big mods.
And testing the current version, I was able to replace and remove all tiles.

here's my list

And mine, sorry for delay.

Wow, one of those is a very long list.
Okay, this weekend I'll try to match the mods lists and play around (No promises, it's ComicCon weekend), I feel like there's going to be a similar mod in both your lists that is an incompatibility with mine for whatever reason. If I find it I'll update here and on the info page about it.

Hope you enjoyed ComicCon. Any luck tracking down why a couple of us cant pick up the flooring?

It was fun but busy, I'm working on it now and nearly got all the mods from one of your lists. I really should have asked for a save file as I could have just synced mods with it :/
if neither of you mind, I would still appreciate a save as my tests will be done in sandbox mode which will be a different situation compared to where you both got to.

Great, it looks like SE is the issue. I'm fairly sure it was compatible in the early stages but I must have not tried removing the flooring. I'll look a bit closer into why SE is stopping the tiles from being replaced because as far as I can tell, my tiles are the same as concrete and should behave the same.

With a little help from the SE discord, the issue should be resolved. I'll push out the next update today and it should make the existing flooring be removable/replaceable.

Thank you so much!
