Are there any major contradictions in the various Legends stories set during the Rebellion?

Fans of the expanded universe know that there are huge contradictions, both logical and purely factual, between, for example, the first six seasons of The Clone Wars and other works that take place between the second and third episodes. For this reason, many believe that The Clone Wars should not be in Legends in any form, even the early seasons.

However, I have a question. Is it only in this era that there are glaring contradictions between the Legends?

Is there anything similar, for example, for the Rebellion era? After all, from 1977 to 2014, a huge number of works were written about this period. During this time, values, moral guidelines were changing, some things were forgotten and others were brought to the forefront...

Are you aware of any inconsistencies in various works of Legends, which take place during the Rebellion era?
