Note that removing a layer does not change the player save data in any way, so you can safely add and remove the same layer. In fact, there is a <code>reloadLayer</code> to do just that, which is used for when the structure of a layer changes - e.g., adding a new feature.</p><p>If you're going to be procedurally generating layers, all with a similar structure, it might make sense to use a utility function like the following in order to easily access a correctly typed reference to a layer with a given ID:</p><div class="language-ts"><pre><code><span class="token keyword">function</span> <span class="token function">getDynLayer</span><span class="token punctuation">(</span>id<span class="token operator">:</span> <span class="token builtin">string</span><span class="token punctuation">)</span><span class="token operator">:</span> DynamicLayer <span class="token punctuation">{</span>
