I was building a gate, and then I went to my lake house for the weekend... when I went on (just a while ago) to check to see if it was done, it was, though I dont see it anywhere and I have no resources.. Really ticked and I need my Gate back. This was a period of 3-4 days, if that helps any.

Gates is a type of machinery. It looks like a mine builder. You move it to the designated place and then the "Build gates" button appears.

Yes I know it look like a machinary (like mines)... But it just didnt show and now that im on a second time it just randomly appears... Huh.

I've built the gate and moved it to location but it doesn't give me the option to build it into a proper gate. What is going on is it glitched on me?
