I loaded in and all light switches are missing as well as a few tiles . Any suggestions ? Worked fine previously

@FadedXJ Do you have all the tile packs in your server and your game?

I'm getting a lot of "WARN : General . . .Spawnpoints" errors in my sconsole.txt file. In addition to this mod I have Better Occupations and Overfield Bunker; I guess there might be a conflict among two or more of these mods? I presume are what cause the little red Warn box to pop up on the lower right. Pretty much new to PZ (played it years ago but only about 20 hours). I hear of "errors corrupting saves. . . but not always." Are these errors something I should be concerned about?

Always when i load the game, some walls are missing, any fixes?
