The list of bugs and glitches introduced with the Summer update is long and the majority only manifest themselves in PLAY mode I will list the more noticeable ones:
1 - Trees and other foliage placed near pools are launched into the air on entering a build
2 - Selling anything near an item hanging from the wall causes it to drop to the floor
3 - Selling or deleting (trash collecting) anything near preloaded shelves or containers launches items into the air
4 - Sinking a 'packing box' into the ground causes it to disappear completely
5 - A random square of water can appear at ground level close to a pool and cannot be removed
6 - Items placed with the MOVE tool so they appear to float on water sink to the bottom (this is necessary because none of the 'floating' pool items actually float!
These bugs alone have caused creators to spend HOURS 'fixing' their custom builds, replacing the water was one thing we could have coped with but all the other issues that came with it are TOO MUCH!
This needs to be investigated URGENTLY and something done so creators can get back to creating instead of repairing!
