Bug: I filled up my furnace output area with finished products (99 items in each) and suddenly the game started crashing it directed me to /minetestgame/mods/default/init.lua line: 1411 unable to concatenate string "item" (this may not be the exact message but it has all the pertinent info i believe) i commented out that section and was able to get back into the game to remove the items from the furnace then uncommented the code and continued playing.
Glitch: i have a stack of dirt on one of my maps t hat i had discarded at one time now it wont go away and each time i try to pick it up it gives me 41 dirt and gave a warning about a "static object" now each time i click on it it says:
singleplayer punched object 1 at [location],
singleplayer punched object 2 at [location],
singleplayer punched object 3 at [location]
Etc. etc.
Great game btw hope i can help out some more ^^
(sorry about not getting the verbatim warning messages i didn't think about it when the happened)
