This problems are still not fix, insterad the got worse again afgter removing the refresh button. Now you need to use the ?v= and hope it works. well sometimes it works and sometimes it not works.
Then after finaly with lots of annoying numbers you got the entity a bit placed. Then you think. something is wrong. so you increase ?v= and then it seems your using the old cached one. That for some reasonb where wrong positined and palced too.
Anyway a mystery why the same object get everytime loaded at different position. and you can start the palcement hell over again.
I really hate the cache in edit mode.
