Island living glitches.

my sims are walking on the ocean water and also odd jobs never work out. as in when I accept the odd job when it comes time to go to that job it never gives the option to go if that makes sense.

Go to Documents\Electronic Arts and move The Sims 4 folder to desktop. This will start the game fresh, you can move saves back later. If that doesn't solve the problem, run the validator and post the result here.
