Since the last update (1.1.18), sometimes, when I attempt to place a requester train stop via a blueprint or copy/paste, all I get is the train counter, and the requester itself is completely invisible. The odd bit, is that while the counter is there, you can't right click to remove it, drones can't remove it, nor can you right click on the square where the requester train stop is usually located in relation to the counter to remove it, you end up removing the tile underneath.
The only way to actually remove it is to place another requester manually, in the exact same spot - which clears it, then place it a second time to place down another stop.
I don't know if this is a conflict with other mods, I do have quite a few in place, the only thing is that I've only updated TSM, and prior to that update it was working.
I don't know how to provide screenshots to this post, as it does not appear like I can copy/past any.
