What do the map changes do the 2.7.0 patch notes refer to?

[NovaScienceNever]

Here were the map changes that were listed.

• Saltspray Rig: Adjustments to prevent players from taking certain shortcuts in all modes.
• Bluefin Depot: Fixed a problem where players could go inside a certain object in Rainmaker mode.
• Flounder Heights: Adjustments to prevent users from taking certain shortcuts in Tower Control mode.

while I know what the one for bluefin depot is referring to, I don't know what the other two involve specifically

I can answer the middle one to you.

Doesn't save Saltspray Rig from being a terrible map.
