Hi just recently started playing the game, been following the past update and now currently playing the new version...
Sadly once you get to a certain size you simply cant interact with the nuclear waste barrels anymore, you need to make the interaction field for them bigger, I can still interact with people and cars fine though.
Just the barrels I cant after the second one is eaten.
Kind of a shame really but the new update is fun the play, so keep it up and keep on improving this game :D.
