Some scores in TwinDuel have shifted a lot

I'm noticing that some of LunarTwins' scores in TwinDuel have shifted dramatically from what they were as of RumbleArchives:TwinDuelRumble_20200126, despite the robots involved in said pairings not having been updated since. Particularly versus the following four:

• bvh.two.Valkiries 0.44tmk3b
• bvh.two.Ravens 0.2
• gh.twin.GrauwuarG 0.41
• krillr.mini.JointStrikeForce 2.0c

which are four bots that have been unchanged since 20200126, that LunarTwins used to win decisively against, but appears to no longer do so in the TwinDuel LiteRumble. Also appears those for some reason appear to have had their pairing count versus LunarTwins reset more recently than some others for some unknown reason? Not sure. I'll be looking into it more some time, but it makes me wonder if this was due a change in robocode version.

To update, it seems robocode version 1.9.3.8 through 1.9.4.1 had entirely broken getTeammates/isTeammate, which breaks various TeamRumble/LiteRumble bots, including but surely not limited to LunarTwins.

This bug appears to have been introduced to 1.9.3.8 as a side effect of the fix to this bug.

Version 1.9.4.2 fixes a bug with getTeammates/isTeammate.

So Skilgannon if you're reading this, we should probably update the literumble version to 1.9.4.2, and also clear all TeamRumble/TwinDuel pairing data that was from a client with one of the flawed versions. Given things appear to have went from 1.9.3.5 to 1.9.3.9 in LiteRumble, it looks like it's just the 1.9.3.9 results that need to be cleared from TeamRumble/TwinDuel pairing data. :)

Rumble is updated to only accept 1.9.4.2. I will wipe the Team / TwinDuel, unfortunately they aren't stored by upload version.

Thanks for the prompt response! Should be able to get the pairings built back up again pretty quick I think.
