Old Blueprint Code which does not exist anymore is disturbing the game testing

Hello, i have a big problem.
We have made much progress and our project rises but we have the problem that old written blueprints that are not in the project anymore are still in the preview…

We are using the c++ version but most stuff we currently building with blueprints.

In the game preview it prints out screen variables which blueprint/code is not there anymore but be were unable to find a solution…

Any ideas?

Thanks and best wishes!

someday my computer shut down because of updates and the editor crashed… maybe this has caused it?
i give you an example:

i wrote a pawn class and rotated it in the tick event tested the code by hitting play and after testing i deleted those parts so it won’t rotate anymore but i still see it rotating sometimes !?
i even copied the blueprint first with the copy function and after that failed by result, i created a new one and copied it manually by typing it…

who can help me? what do you need?
im not sure but the problem could be only in the project…

after i noticed that there is something wrong with the project, i created a new one and copied all assets into it… since i copied the blueprints i noticed the same

dang i was so stupid, i found that piece of code… everything is right now.

sorry!
