The official drop tables located at https://n8k6e2y6.ssl.hwcdn.net/repos/hnfvc0o3jnfvc873njb03enrf56.html are missing some info after the recent updates.
For example, searching the text for "Heated Charge" shows only nine entries--all entries specifically for rotation completion awards of Heated Charge.
The mod entry itself is missing, so we are unable to see which enemies drop the mod on kill, and it would seem that the enemy mod drop tables are missing as well. Other examples of missing info from the drop tables include "Deep Freeze", "Convulsion", "Pathogen Rounds", "Target Acquired", etc.
This info was all present a week or two ago, as I used the information to update the mod drops on the wikia pages for the newly added Nightwave enemies (Zealot Proselytizer and Zealot Herald). You can explore what I mean by visiting a cached version like this Wayback snapshot of July 24th 2019.
While mod drops are still shown by mod and by enemy in game in the codex, it does not display exact chances, and therefore I am unable to add the new information to the wikia until this is resolved.
(EDIT: It appears mods are not displaying correctly in the Factions Codex, which is most likely related to the bug in the drop tables)
