Essentially they got into a match that went on for a few hours, and both took action to ensure they couldn’t lose. As you can imagine this means taking out most of each others military, villagers and buildings. Then the wood on the map ran out, and they both ensured no monasteries were left standing so they couldnt event get relic gold. They both ended up with a castle, a few military units but no seige.
After that they just stared at each other, waiting for the other to give up and disconnect. This was the vast majority of the 95 hours, but I don’t think either were sat there for most of it.
Then 95 hours in Rubenstock lost connection.
