It is not stuck and to give you a comprehensive answer around the source of fees see below:
- The Bancor Arb Fast Lane which is deployed across multiple blockchains directs 50% of the arbitrage profits back to the Bancor protocol. These fees collect in a vault and then eventually get sent to the vortex in order to be consolidated to a single token.
The fees metrics for the Bancor Arb Fast Lane can be found in Dune (see link below) for most of the blockchains where it is currently deployed (although there are a few that are not there yet due to no Dune support for those blockchains)

You can read more information about the vortex and what it does here:
- Carbon DeFi also collects fees when a strategy gets executed which the taker has to cover. The fees for Carbon DeFi are also on Dune in the link below:

These fees are also sent to the Carbon Vortex in order to be consolidated into a single token.
To track the balances that the Vortex has, you can check the following smart contracts below. There are more addresses but these are currently the ones that get utilized the most and therefore see the most amount of fees.

The above covers the new flagship protocols of Bancor but there are still legacy protocols of Bancor on Ethereum (these are mainly v2.1 and v3).
The v2.1 protocol sends its fees to the Bancor Vortex on Ethereum (the address is listed above). For Bancor v3, the fees collect under pendingnetworkfeeamount as you have already figured out.
This should cover all the fees in the Bancor ecosystem.
