Fix simsetting bug

[Ziidy]

Wait for frontend and test with that branch!

Test the following:

• Make sure that the current setting is used when running the simulation, easiest way to check this is changing end simulation and check x-axis.

I got a bug once that I have not been able to recreate, only thing I can imagine is that my hardware was too slow once since my computer was very buggy. I think it happened when:

• test 'end simulation' with high value (200) and try picking a lower value. Then try the same (200) and test with a higher value.
