Stag has been updated to beta 2. The list of changes is as follows. Some major balance changes were needed, so they are now in place. Additional tweaking will be made as needed for future versions.
BETA 2 CHANGES/FIXES:

-Changed map timer to 9 minutes instead of 10, since it’s smaller than other 5-point maps.
-Default spawn timers changed to ~15 seconds max instead of the 9 they were at.
-Players who capture the enemy’s 4th CP will have a slight spawn timer reduction to compensate for absence of second forward spawn.
-When a team loses their 2nd control point they will no longer be able to get out of their front CP2 spawn exit. This makes it slightly easier for offense to hold, and encourages players to retake the point. Signs in the spawn room change accordingly so players don’t get confused when this door locks.
-Middle cap point timer changed to 24 seconds for 1 player (Granary default) instead of 30, so players can reclaim the middle easier.
-Final cap timer changed to 8 seconds for 1 player instead of 12 to conclude the game slightly easier.
-Underground tunnel system has been widened, so it’s no longer as cramped.
-Two small health and ammo packs added to the sides of the sniper deck to help players retake the middle CP.
-Outside has been optimized more.
-Ladders in the sewer raised to avoid confusion about being able to use them.
-Red logo in sewer resized correctly.
-Players running along the ledge outside will no longer get stuck at a point.
-Some additional signs added to clarify paths (like the small ramps up in the box room as an alternate method to get up).
-Spawn doors no longer have intersecting brushes when open.
-Reduced brightness outside slightly. Download:
