Changelog:

Efficiency bugs improved
Ore Panel updating improved (again)
Nuke Frame crash refixed, hopefully
Added mouse panning (for shipyard mode only)
Added new Plan - Listening Post Base
Added Swarm Select ability. Left click and hold on the currently selected bot, a select circle will grow out if it. Release when it's large enough and any bot in range will form a defensive swarm around the selected bot.
Coming soon: Dungeons, Wormholes, Shop Frames and more! The Game Guide is also continuing to be updated, check back back every so often for more.
