V8.25.1

Features

• #618: when another player enters a puzzle while you are running it, you now receive a chat message telling you who entered and that your run will no longer be eligible for records.

Fixes

• #624: a cube sitting on a Cube Pressure Plate once again blocks lasers (and, for concentrator cubes, re-emits the absorbed laser in its facing direction).
• #625: rapidly re-pressing a Cube Creation Button while the cube was still appearing no longer leaves a stuck barrier block under the distributor.
• #626: a held cube can no longer pass through walls or ceilings — when something is in the way, the cube now hovers right in front of the obstacle instead of slipping behind it.
