A trigger with a wait running for the same player with another wait block trigger. If you have a wait and then while checking other triggers on that wait, encounters another wait, your triggers will seem to lag.
I guess liek this:
| Trigger |
| Conditions: |
| ¤ soemthing |
| Actions: |
¤ do soemthing
|
¤ wait 2000
|
¤ do something else
|
| ¤ preserve |
| Trigger |
| Conditions: |
| ¤ true when trigger #1 is true |
| Actions: |
¤ do something
|
¤ wait 2000
|
| ¤ do something else |
