Patch notes for v0.8.6b and v0.8.6c

v0.8.6b

• Fixed a possible game freeze in highlight rendering and restored the tower highlight on area hover that was temporarily disabled because of it.
• Fixed transport highlights that could get stuck or attach to the wrong transport right after an upgrade.
• Fixed an error when splitting a transport that had a pending downgrade or replacement.
• Fixed transport previews not being removed after canceling a drag placement.
• Fixed a stranded pause icon when demolishing paused transports.
• Fixed aprons flattening nearby terrain that they should not affect.
• Ramp entrances no longer flatten terrain under their open areas.
• Auto-placed surfaces now override buried surfaces, so a building placed over a dumped-over surface gets its surface properly.
