Removed my minishield from where it was protecting the SP (just above where I'm standing in SS), and then built some stuff beneath it. I'm not sure whether the container of CHIMPs was irresponsible or not but as you can see this was also removed.
I think Hola was acting in retaliation from where I removed their container from lower in the water earlier in the game. However when this was done a container was built on its own which left it vulnerable, if you are going to fortify that far outside of your base you must save up and build the SP at the same time as the container or else it's a leech. And where this stuff was built low in the water it all got killed very easily as the builds made it difficult to hit enemies.
