Here is a thought.
If all the crowdfunders cash was deposited in DJM’s personal account/PayPal rather than a business account and he subsequently transferred that cash into the business, could that not explain the £50k Director loan?
In the books, the money came from him, but it was actually YOUR cash and he becomes the creditor a bit further up the tree from the individuals.
IIRC, the £50k could also be what he thinks he is owed by the business for his time/salary/dividend from the business.
