Conflict-free Replicated Data Types (CRDTs) can simplify the design of deterministic eventual consistency. Considering the several CRDTs that have been deployed in production systems, counters are among the first. Counters are apparently simple, with a straightforward inc/dec/read API, but can require complex implementations and several variants have been specified and coded. Unlike sets and registers, that can be adapted to operate inside maps, current counter approaches exhibit anomalies when embedded in maps. Here, we illustrate the anomaly and propose a solution, based on a new counter model and implementation. ; Project Norte01-0145-FEDER-000020 is financed by the North Portugal Regional Operational Programme (Norte 2020), under the Portugal 2020 Partnership Agreement, and through the European Regional Development Fund (ERDF).
