Pokémon TCG 2, Here Comes Team GR (Artemis251's translation). Always get timed out in Link Battles.

Even if we're fast, we can only seem to make it to the set-up phase of our (same PC, 2 windowed) duels before the game in Player 2's window says "There was a communication error. Please try again from the start" and then Player 1 receives the same message and is kicked as well. Most often though we're too slow and can't even get past picking the prize count for the duel. First time on here, so I hope this is all sufficient.

to add to this, the original jp version appears to suffer the same issue, and the exact point at which the communication error occurs seems to be inconsistent, although i was able to orchestrate the duel properly within bgb, in both the original and Artemis251 translation patch

i hope this info helps :D
