There is no simulation script. Please check that your scripts are in user-files/simulations

I am using Gatling 3.0.3. I wrote some scripts yesterday which were working fine but then they stopped showing in simulations when I was trying to execute using command prompt. So, I deleted those newly created simulations. And now when I try to execute ./gatling.sh via CL, I am getting the erro:

There is no simulation script. Please check that your scripts are in user-files/simulations

I have no idea as to why this is happening as it was working totally fine yesterday and I have not made any other changes. Please help!

I reinstalled Gatling and that took care of the issue! Weird!!
