As this is just a small edit to the True Directional Movement mod, I'll defer to its permissions. Basically, do what you'd like with it as long as it's on Nexus, and not being sold.

Changelogs
Version 1.3
Added ice wraiths, and an alternative mammoth for Rougeshot's skeleton. Also adjusted the text format now that I know TDM will read any .toml file in the proper folder - Thank you, eaqQpnkbxpm1irzxfp, for pointing that out to me!
Version 1.2
Fixed FormID error in Bristleback text.
Version 1.0
Reverted the version number since I've changed the approach I'm going with. Added mammoths, with an additional node in the vanilla skeleton which is then targetable. Removed the "TrueDirectionalMovement_base.toml" file that was in the Bristleback file, and instead added instructions on the main page to find the base file in TDM in which to add the target node text that is included with each file.
Version 0.9
No longer requires my personal main plugin as a master. Woops!
The lock-on feature for True Directional Movement is great, but there are cases where it doesn't automatically point to the correct location, such as Bristleback boars where it aims at the Riekling rider who may not actually be present as the skeleton is shared by both the lone boar and the one with the rider. This will be a collection of fixes and adjustments, which may include things like adjustments to skeletons, ESL-flagged plugins, and additional target toml files for TDM.
Some modded creatures are also affected by the changes to vanilla creatures because they are based on vanilla races, and thus share the BodyPartData. One example is Mihail's Czarts/Howlers, which share data with the Bristleback and thus also have their targeting adjusted by the same file.
