This mod adds personal Teleaporter to the game. A lot of Thanks to iUltimateLP and his mod SimpleTeleporters for inspiration and for the use of His Code and graphics
I host a server, with one other person in it. I can expand and collapse the Teleport menu, but when the other person does, Factorio crashes. This occurs regardless of whether the person in question has a personal teleporter in their inventory.
At no point does this issue reproduce with me, the server host.
