I made a pull request of trunk-4986 but i mistakenly sent it to the master branch of the folk seen HERE.
Any advice on how to make a new pull request because i had already made the changes required? how will i be able to make another PR yet the changes have already been pushed?
I think you should follow what @mozzy has said, make sure to also avoid making changes on master, and make a PR to openmrs/ openmrs-core master branch instead of master branch of your fork
its better you close it , because it may be more hectic to cean it up , than to just create a new one.
Good thing you can always create new 1000 PRs at a free cost
