1v1 Tournament and Matchmaker Fixes

A standard 8-16 player 1v1 single elimination tournament will be held this Saturday. Sign up in this thread: https://zero-k.info/Forum/Thread/25420

In other news, our lingering matchmaker issues have been reproduced, fixed and deployed. The fix of a few days ago was accidentally not deployed due to a database problem. Please report any issues.

Zero-K v1.6.5.1 - Balance update

We have taken a look at games and feedback and come up with a small balance update. Inconsistent, and sometimes drastic, unit interaction with gravity guns and other sources of impulse have also been fixed.

Glaive is now slightly less cost effective, but their behavior is unchanged.
  • Cost 60 -> 65

Welder was dealing a lot more damage than intended, possibly due to an engine update or fixed scripting issue.
  • Cost 220 -> 230
  • DPS 72 -> 45

Pyro may now be more effective in groups.
  • Now avoids shooting through allies.

Constable is lighter as an experiment.
  • Cost 160 -> 130
  • Buildpower 5 -> 4

Seawolf escaped the ongoing sea changes:
  • Cost 200 -> 220

Shogun has a respite from the recent nerf, which was a bit too far:
  • Reload time 15s -> 12.5s

Zero-K v1.6.5.0 - Fancy shields

The fixes and features have stacked to the point that it is time to make a content release. The most noticable change is the much improved shield shader, which only just missed out on inclusion in our initial release. A notable fix is to overkill prevention against healing targets as this was reasonably easy to trigger with light artillery.
  • Added fancy hex grid shield with a wobble effect on impact.
  • Improved Ramp terraform tooltip to make it clearer how to change height.
  • "Exit to Lobby" resigns. If you want to leave and reconnect, for whatever reason, go to Lobby (F11) and press Leave.
  • Default to All Chat when you have no teammates.
  • Added a button to the top left of the UI for defence range settings. Added a setting to draw scouted radar ranges.
  • Updated Kamikaze trophy icon.
  • Fixed some main menu tooltip bugs.
  • Fixed some reconnection detection issues.
  • Fixed low command visibility settings.
  • Fixed Guardian steel skin.
  • Fixed overkill prevention against targets which are regenerating or being repaired.
  • Fixed various minor bugs an errors, especially relating to save/load.

1v1 Tournament 18:00 UTC, Saturday 5th May

Ladder play has been so popular that we've decided to run a short 1v1 tournament this weekend, just to get into the swing of things. The format is single elimination within pools stratified by rank. Everyone should be able to sign up and have a decent chance within their pool.
