A weird issue about event system

one of my coworker made some event in VS by UE4 standand,and use it at UE4 standand(Broadcast),but when i download it(.h&.cpp) by SVN,there has one event can’t be found in blueprint, and another event what i add after download is can’t be find too,i tried recompile but useless…
and weirdest thing is only my computer has this issue when VS‘s Solution configuration in “Development Editor”,in “DebugGame Editor” is ok.
i think the reason is some UE4 or VS setting,but i change nothing befor…
does someone had similar problems????

Have you tried regenerating the VS solution? New files need to be added to VS solution as well. Right click on the uproject file and click “Generate VS files”

thanks;yes i did,but useless…now i’m downloading whole project again…but i really want to know reason…
