createExpansion can return undefined townhallPosition

[grifinas]

// main.js
import { createAgent, createEngine, createPlayer }  from '@node-sc2/core';
import { Difficulty, Race } from '@node-sc2/core/constants/enums';

const bot = createAgent({
    async onGameStart({ resources }) {
        const { units, actions, map } = resources.get();

         map.getEnemyMain(); //throws error 
    }
});

const engine = createEngine();

engine.connect().then(() => {
    return engine.runGame('RoyalBloodAIE', [
        createPlayer({ race: Race.RANDOM }, bot),
        createPlayer({ race: Race.RANDOM, difficulty: Difficulty.MEDIUM }),
    ]);
});

error looks like this:

TypeError: Cannot read properties of undefined (reading 'NaN')
