I'm getting some image errors in the log when I open up the crafting menu.

If it doesn't affect the mod in-game, it should be okay. I'll have a look if I might've typed anything wrong, but it might just be the mod lacking proper images in some places.

This is a nice mod, however while I can lie down on the spots just fine, for some reason they don't seem to restore my health like a normal bed does...?

Well, it makes sense for a spot on the ground not to provide any benefits (:P), but I also didn't want the health particles to show up so you could maybe hide your character for RP sake.

Oh so it's intentional? Okay, didn't realise that, thanks for the info. I was going for a sort of tribal character who is used to sleeping out in the wild, and I thought using this as a bed would suit that, but no worries^^

When I have time, I may make a version that allows healing. I'll just have to figure out which code I deleted :D

can you move where the player lays 2-3 blocks over?

I understand placement is problematic, but I currently don't mod Starbound and focus on other things. If I return to modding Starbound I will try fix this

So I cannot use this mod on my server, it breaks every time I start the server. Now the error is in this log file

Now I have taken the time to make a fix for this error, which I tested 1.3.4 and I have tested in 1.4.

This issue has persisted as long as I can remember with your mod, and does it both on linux and windows.

Here is the fix in a patch file format:
https://pastebin.com/1UtfrK2y

This fix should be applied to both of the files called "dglspot.object.patch" in /objects/generic/groundlayup and /objects/generic/groundlay

Thanks for your report @thakyZ and I incredibly appreciate you providing a patch for it.
I'll fix this issue as soon as possible.
