Resource cost highlighting doesn't occur if a resource hasn't been unlocked.

Lowering tax rate below "low" sets it to undefined which behaves as a tax free mode.

There's no visual indicator on the map that indicates what locations have been prospected. Without this it's easy to lose track of where you prospected.

Coal in this mine went negative

This appears to be related to lowering the resource quota while the mine is low on that particular resource.

There's an apparent logic fault in this block of code as it doesn't check how much resources are left in the mine before subtracting the excess

if (town.quota[res] && harvesters > (town.quota[res] - town['storage'][res])) {
    if (mine['manager']) {
        var excess = harvesters - (town.quota[res] - town['storage'][res]);
        global.money += excess * global.resource[res].value;
        mine['resources'][res] -= excess;
    }
    harvesters = town.quota[res] - town['storage'][res];
}

Once electricity is researched huts are replaced by houses, but the hut graphic on the map remains even though these are now houses.

Lets say I have a non-manual labor resource (cement), if i click on it, it opens a tooltip bubble to sell (assuming i have a trademaster), if I then sell all of that resource, the resource disappears. But the tooltip bubble remains and never goes away.

Shim for slider.js doesn't work.

If the fallback.js functionality is needed this might not load in the correct order causing potential unwanted behavior; the shim functionality in the fallback routine should ensure this loads correctly but adding it always causes the file to not be loaded at all, unknown why.

...when a mine is depleted and cleared.

Automatic production halts if the city storage is at capacity preventing some valid transactions from processing.

Example 1: City storage is full, the player has some amount of stone and a cement factory with workers assigned to it but the stone stops converting to cement even though this should be allowed because stone is decremented from the storage making room for the cement.

Example 2: A manager is assigned to a factory which should automatically sell excess resources, but they stop doing so if storage is full. In this situation the unstorable resources should automatically be sold but instead are prevented from being produced.

Managers aren't dependent on the Trademaster, even though the trademaster is what unlocks selling of goods.

Currently it's only possible to dispose of unwanted mines, but most structures except the town hall should have an option to destroy it; this is especially necessary for storage type buildings such as houses and sheds because they have no limit and the player could overfill the map with them blocking progress by having no free space to build in.

hi, I don't know if you'll read this but here goes.
I searched your github because I liked evolve and was wondering where I can play Empire. I tried opening https://pmotschmann.github.io/Empire/ but all it showed me was just a blank white screen with a menu and city button (city has nothing, menu has import and export functions).
and I was wondering where I could play it, if possible

Thanks

Doesn't appear to be a visual glitch that I can see, but the console throws this error periodically.

Uncaught TypeError: unwatch[id][("storage" + key)] is not a function
    at empire.js:186
    at Array.forEach (<anonymous>)
    at empire.js:165

I'll see if I can figure out what is causing it
