For some odd reason, the texture colors for all Seraphim units don't match their team colors - both friend and foe alike. To name an example, a recent game had me play as a mint Seraphim, but all my units were yellow. Does anyone else have this bug? If any of you ever had it and fixed it, please share.
I recall having this problem sometimes on medium fidelity. You can try switching to high fidelity in the graphics settings, but I don't remember if it is a persistent problem or just a bug. So try deleting the cache first.
