My dialogue crashes when a character spawns with "At the position" greater than 4.

[EmmanuelHuazo]

When the value "At the position" in the timeline editor is greater than 5 it crashes my game.

Describe the bug
As I already said, I was playing with the positions that the character can have and I discovered that if a character uses a value greater than 4 (5,6,7,8,9, etc) the game crashes.

Also, it seems that putting a negative value doesn't move the character to the left.

To Reproduce
Steps to reproduce the behaviour:

1. Just put a value bigger than 4.
2. I was using 3 characters at once.

Expected behaviour
it crashes.

This is somewhat "expected" as the default scene only comes with 5 portrait positions.
Ideally there shouldn't be crash, only a warning.
