navigation invokers not working in the packaged builds but works perfect in the editor

(this is for 4.21)
hello i am having a huge problem with ai navigation invokers not working in any packaged build but generates and works perfect in the editor itself and i tried many different things to get it to work with no success. The very strange thing is that for a long time at the start until now it was working perfect in the packaged builds but all of a sudden it does not work anymore. It seems like a big glitch in Unreal Engine itself, i really don’t understand what the problem could be all of a sudden, what could i possibly do to fix this headache, there is a persistent level with the sub levels having the nav mesh and it was all working perfect but now for no reason at all it does not work in packaged builds now

i didnt fix it. i went back to a close old version of it working and i have it all back up to the latest version with invokers working now so i have really no idea what happened with it but at least its working now, what a headache that was :frowning:
