So, let's say your town is underground. You get a whole bunch of shards and go up to the surface to pay your taxes, and.. wait what's this? Raid and you're dead. Now you don't have enough shards to pay your taxes and your town dies. This may be overdramatic but it's just my example. Once you reach a certain town level you should be able to move your tax chest. There should be a feature much like /g chest but to get your tax-paying chest down. A command like /g i chest where you can put your chest anywhere like it's a town portal. I think this would be a good idea so things like e.g. doesn't happen.
