If I run composer update into bigland/yii2-models-conceptual-plan repository - everything is fine.
If I run composer update into bigland/yii2-models-catalogue repository - I have the following error:
Problem 1
- bigland/yii2-models-conceptual-plan dev-master requires bigland/yii2-models-catalogue ~1.0.0 -> no matching package found.
- bigland/yii2-models-conceptual-plan 1.0.3 requires bigland/yii2-models-catalogue ~1.0.0 -> no matching package found.
- bigland/yii2-models-conceptual-plan 1.0.2 requires bigland/yii2-models-catalogue ~1.0.0 -> no matching package found.
- bigland/yii2-models-conceptual-plan 1.0.1 requires bigland/yii2-models-catalogue ~1.0.0 -> no matching package found.
- bigland/yii2-models-conceptual-plan 1.0.5 requires bigland/yii2-models-catalogue ~1.0.0 -> no matching package found.
- bigland/yii2-models-conceptual-plan 1.0.4 requires bigland/yii2-models-catalogue ~1.0.0 -> no matching package found.
- Installation request for bigland/yii2-models-conceptual-plan #dev -> satisfiable by bigland/yii2-models-conceptual-plan[1.0.4, 1.0.5, 1.0.1, 1.0.2, 1.0.3, dev-master].
Potential causes:
- A typo in the package name
- The package is not available in a stable-enough version according to your minimum-stability setting
see <https://getcomposer.org/doc/04-schema.md#minimum-stability> for more details.
Read <https://getcomposer.org/doc/articles/troubleshooting.md> for further common problems.
Why is this happens?

Answer 1

Isn't it strange that you've a circulair dependency? A -> B -> A

Answer 2

The solution is following: replace circular dependency versions to dev-master instead of 1.0.x.
bigland/yii2-models-catalogue Conmposer.json
"bigland/yii2-models-conceptual-plan": "dev-master"
bigland/yii2-models-conceptual-plan Composer.json
"bigland/yii2-models-catalogue": "dev-master"
