this is another small glitch that allows doing something that's probably not intended. If I have one person in the teleporter bay, send more to join them, click on the teleport icon before the shield drone charged the first level of the supershield, and then wait with the teleporter icon still active until the rest of the crew arrives, then it's possible to teleport crew past the enemy's supershield.
Didn't take a screenshot - but hope it's clear what I mean, anyway
. I.e. if the game would check if there is a zoltan shield active when I select a room to teleport to (and not only when you first click the teleport button) than this wouldn't work.
