Jar Jar event tier 4 (Darth Maul)

I saw many reports on this and no official answer. You get to tier 4 on Jar Jar Binks journey guide, and turn 1 Maul just one-shots Jar Jar making you lose before even getting your first turn.

I can confirm it still happens most of the time, and when it doesn't, Maul just gets free turns anyway and eventually lands an attack on him that deals massive damage. Everyone else gets defeated in 3 hits AT MOST too.  What is going on?
