+// In the transporter room, several scripts attempt to temporarily set ego's
+//  speed to 6 but instead change the game speed. This prevents ego's speed from
+//  being restored. The user must then do this manually in the control panel.
+//  These bugs are due to calling ego:setSpeed instead of ego:cycleSpeed, which
+//  we fix. This occurs when randomly beaming in with the funnyBeam script and
+//  when talking to Cliffy about Bea before curing her.
+//
+// Applies to: All versions
+// Responsible methods: funnyBeam:changeState, talkAboutBea:changeState
