Setting Inapplicable Back Button Hangs Player

[Enthalpy]

If "show back button" is selected outside of a psyche-lock for a "player's input" command, the player will crash when it gets to that command.

Ideally, the editor would be smart enough not to even show that option outside of a psyche-lock, even in advanced mode, but alas.

The editor is smart enough already, and show back button is not displayed outside of psyche locks frames.

Unless, of course, you check the Advanced mode, which basically disables all dynamic checks and lets you set all the action parameters directly - but this mode is clearly indicated as "use with caution", so...

The only way to improve that would be to enable dynamic checks partially in the parameter editor. More precisely, the editor should be able to evaluate all conditions which are not based on any expression-defined parameter. In order for this to work, we'd need to add a feature to the expression engine which returns the name of all variables used in a given expression, and to revamp the parameter editor so that the advanced mode would no longer be needed...

Not a very simple task.

Made the report more precise, per Unas's comment.
