>>38424613>>38424701this is because the turn order is switching in these replays.
In the first one you protected on a scarf durant, and in the second scolipede speed boosted past you
I believe (I may be wrong here, I am trying to read this from the PS github) that showdown checks the staleness conditions for triggering EBC by looping over a list of active mons.
If you change the order of this list, you end up doing the EBC check in the wrong order, so it doesn't work.
