In a multiplayer game the Warp Gate stopped working (no longer allows players to use it to teleport) We think the breakage happened after it was nommed by biters.
it's your solar productivity mods that breaks the teleporter: each time you research a tech, the prototype is changed and then it breaks the link between teleporters (as warpgates are accumulators).
If you reomve the mod, it works fine. You can also request the mod owner to update his mod to include my warpgates in some exceptions
