Summary (AI)

Patch 0.1520 for Space Imperia 4X addresses several gameplay and UI issues. Bombardment now leaves visible damage on planets, and destroyed planets by doomsday machines feature new visuals. Fixes resolve problems with ships firing twice in one round, doomsday machines incorrectly reverting class for firing, and undiscovered planets being destroyed. Improvements were made to fleet visibility and behavior during combat and turns, along with corrections to terraforming reveals and decoy labels. Additional fixes include resolving game hangs in Simultaneous Start mode, restoring accessibility to certain ship sizes in the tech and economy screens, and enhancing transparency in turn order bids across all players.

Tip: expand all for quick scanning.

a scan you chose to keep face down can now be explored again
destroyed ships no longer linger on the board as clickable targets that refuse every shot
fleets revealed in combat stay face up until the start of their owner's own turn at their own colony (5.11)
Blood Brothers allies re-hide their revealed fleets on their shared turn start, and solitaire alien fleets stay face up as the scenario book intends
Fixed issue with terraforming being revealed from combat
hidden decoys were missing the unknown label
Simultaneous Start: a game could hang forever waiting on an AI seat
Simultaneous Start: the Economic Phase could be skipped entirely
hexes scanned with Exploration tech and left face down were forgotten on re-load
solo: a lone cloaked raider finding an alien world froze the combat screen
a ship drifted by Lost in Space onto lone enemy civilians now destroys the civilian ships
tech and economy screens on a short canvas had a dead band at the bottom, so the Cruiser and Dreadnought ship sizes could not be bought
every player now sees every seat's turn order bid, not just the winner, and the bids and the winner's pick are recorded in the game log
