On the day of the fork, however, we started noticing odd things happening. During the maintenance of the BCH Bitcore server, we witnessed how the server started losing addresses and transactions. Addresses had negative balances, which should not be technically possible. This caused the initial delay in deployment, as we could not release a Wallet that would use corrupted data.

There are many lessons to take from this hard fork. We will name the most important ones here:
We will not announce support for fulfilment of certain conditions.
We will not announce features to be released for a certain date.
We will assume the code has bugs.
We will take our time to develop the code and avoid mistakes.
