With the release of Odyssey, a new bug has come up, currently all Thargoid Combat Bonds in Odyssey are 1/4th the amount you will get playing Horizons.
If you plan to hunt Thargoids for credits, stick to Horizons for now.
The Odyssey bonds are back to the pre-nerf numbers from before the re-balance a few months ago.
Horizons Bonds:
Cyclops 8M
Basilisk 24M
Medusa 40M
Hydra 60M
Odyssey Bonds:
Cyclops 2M
Basilisk 6M
Medusa 10M
Hydra 15M
Note: This isn't just a visual bug, it appears in transactions as well.
