Updates:
I understand why they had to remove this interaction but I know many also wanted this for their gameplay like I did, so here's this interaction re-enabled for your sims, just click on the shrine and select "Bow". You will need XML Injector for it to appear on the shrine.
I also made an optional add-on that re-enables bowing randomly when sims are hiking. I had taken a look at the files for any other bowing interaction references and noticed this was removed as well. This add-on requires the main bowing interaction .package to work.
Please only choose the Override version or the XML Injector version when downloading. The XML Injector version does not override the object_HikingPOI_CaveShrine and object_HikingPOI_Shrine tuning and instead uses the script to inject the interactions.
The Override version, and the add-on, overrides the following XML and will conflict with any other mod that overrides/alters the same files.
