• Continuing from BUG: Parachute lag warning when lag is 0 #343

• Seems like not all changes required to fix this issue were made. Probably I made some mistakes with git somewhere in the way of importing these changes from the dispersion to a new branch

Anyway, need your review again @giovaniceotto
