The bug with using multiple .Include() in EF Core 2 is fixed. Look forward to the next public build of dotConnect for Oracle.

Is due to your statement:
var entities = helpTopicRepository.Entities.Include(x => x.HelpArticles).FirstOrDefault(t => topicIds.Any(a => a == t.Id));
Assuming that topicIds is a list, here is a fix:
var entities = helpTopicRepository.Entities
.Include(x => x.HelpArticles)
.Where(t => topicIds.Contains(t.Id))
.FirstOrDefault();
