still an issue in 2.5.4. I’m new to development, simple contracts, always getting this error…4/5 times. Go to the contract page to view the contract state:

UnknownBaseContractIdError: Cannot locate base contract ID 1907$ of contract$

Am I supposed to deploy all the base contract intefaces, openzeppelin and such? I wouldn’t think so as they should all get compiled together…

Usually then followed by this trying to reload things on the page where you put your truffle.config file.

PollingBlockTracker - encountered an error while attempting to update latest block:

Then back on main page, all the accounts have 0 eth like they are not loading as well. Ganache just goes into a downward spiral.

Very frustrating, cannot get a solid session going - have to kill ganache and restart, update private keys everywhere, redeploy, update contract addresses again everywhere in my dapps. Any tips/help would be greatly appreciated

+1 to the above. No idea why this is occurring, but it’s hard to tell the difference between real issues and ganache issues with bugs like this.
