We are offered to play a match.

Did Dubrovin Pavel play TE-Lite against an opponent? Was TE-Lite installed on Dubrovin Pavel's computer?

"Interestingly, they were playing Clean SoD. I was the server and using Red Rampart, while Markon was using Blue Fortress. The TE and SoD folders were on different hard drives." (c)

What does TE Lite have to do with it?
It was just a bug in SoD. Which was on Paul's computer.

The fact that some ignorant people write "that it still affects the game if TE is on the computer" is utter nonsense.
