Thanks, the mod conflict appears to be caused by Thallium. Unfortunately, I don't think I can much right now as the Thallium source has not been updated (for several months) for the latest version.

Well it updated today but don't know if the code changed

Ah, I saw that. It does appear that Thallium itself has a bit of a controversial history due to misleading claims and code theft (probably why the source has been archived) and because of that I will probably not fix the issue for it. If you still get conflicts with other mods, please let me know! Thanks.
