Here are my account page details:
CPU Subscription: Active until 2017-12-20 (23 days)
Next renewal: No subscription

There should be no limit on the memory as, that's not implemented.

Could you execute the following line of code in console and report the outcome?

console.log("Shard limits: " + JSON.stringify(Game.cpu.shardLimits));
console.log("Cpu limit   : " + JSON.stringify(Game.cpu.limit));

It should look something like this:

CPU: 0 / 90 
Mem: 464 / 2048 KB

Anything I try to execute - does not work:

console.log("Cpu limit   : " + JSON.stringify(Game.cpu.limit))
JSON.stringify(Game.cpu.limit)
console.log("Shard limits: " + JSON.stringify(Game.cpu.shardLimits));
JSON.stringify(Game.cpu.shardLimits);
JSON.stringify(Game.cpu.limit); 
// no output!

module.exports.loop = function () {
	console.log("Cpu limit   : " + JSON.stringify(Game.cpu.limit));
	console.log("Shard limits: " + JSON.stringify(Game.cpu.shardLimits));
}

You can create a new branch to test this on.

console.log("Cpu limit : " + JSON.stringify(Game.cpu.limit));

FYI: for me Game.cpu.limit returned 150, when my subscription was inactive and the UI showed my CPU is 10. Also my bucket refilled less than 10 units / tick.
