-More Steam Achievements!

-You can now see what Weapons have a chance to drop from a Weapon Data Token at AO:98!

-A hidden mini Sector has re-appeared...

-----------------------------------------------------

>>>Changes<<<

-AO:98 was moved into the Safe Room to avoid Save cheese. It's room will unlock once after every completed loop and relock before the Auto-Save.

-There is a body in AO:40s testing Chamber that will give a hint on how to contain OM:10. (We're working on other ways to hint at the information)

-----------------------------------------------------

>>>Balance Changes<<<

-Nanite costs for constructing Benches has been tweaked slightly.

The Crafting Bench costs 20 Nanites instead of 15

The Modification Bench costs 15 Nanites

Synthesizer Bench costs 50 Nanites

AUX_UTI_ACT Bench costs 80 Nanites

Weapon Storage Bench costs 40 Nanites

Tech Tree Terminal costs 40 Nanites

-Parasites no longer have a weird lag delay when attacking. This was due to their attacks causing a stacking Corrosive debuff that increased their damage on a single target. Now Parasites only deal a flat 10 Corrosive Damage.

-Enemies are Stunned Longer from being hit by Sentry Turrets and Landmines

-Exp dropped from Enemies has been increased slightly

-MOD and ANC Despisers are now Hover Displays with a single confirmation instead of a multi-window navigation.

-----------------------------------------------------

>>>Fixes<<<

-AO:6 is now happy with their toys and is allowing themselves to be contained.

-AO:35 is now longer extending a temporal anomaly resetting its Reflectors. It can now be contained again.

-Procedural generation improvements.

-The changes that were made to "AO rooms now longer call self vars" is what caused AO:35 and AO:6 to break. We're still investigating AO:30, as it has had inconsistent issues too long.

We're working on the RoadMap and will have that out fairly soon Custodians! -Prismatix Team
