Not so sure this is all about NWBO. Here are some excepts from the article:

Mark Carney have noted in recent speeches that some investment funds hold illiquid debt securities.

Investments all stopped withdrawals from the funds devoted to illiquid property assets. Those funds later reopened after markets calmed.

If the stocks owned by the fund are thinly traded or not traded on the public markets, then you know there is always a risk the fund could become as illiquid as its underlying assets.” In other words, you might find that you can’t take your money out when you want it.

Can read some possible NWBO investment issues perhaps but there are specific references to illiquid property assets and debt securities that do not apply.
