It seems that the effects of Infection applied to enemies are being reduced by the player’s disease resistance. Isn’t the player and enemy reversed here?

Found a bug, one of those nasty ones that completely breaks the UI and makes the game go "black-screen":

From investigation, it looks like the problem is in the Decaying temporary effect's .long_desc() method; apparently the eff.dam1 field isn't in place by the time the UI tries to display the effect. (If it helps, the affected character is of the Engineered race from starslayer's Godling addon, which may have some global speed boosts that muck up timing for getting the relevant values into place.)

[Oh, and another small thing while I'm here: if you're planning to stick with shield fighting, I'd suggest adding the following line:

show_shield_combat = 1,

to the .copy{} sub-block of the Infected subrace descriptor (same as the Cursed descriptor has), so that players won't need to enable the "UI | Always show shield combat properties" option to see combat stats for their shield.]

Small sort-of bug to report: looks like you left a debugging log in your Enduring talent, leaving a stream of "There are 0 nearby enemies" as you run around. Only mildly annoying, but hey.

Also, if you decide to keep the Corruption/Doom Shield tree, you'll probably want to explicitly require the Ashes of Urh'Rok DLC by adding the following line to your init.lua:

requires_addons = { 'ashes-urhrok' }

In my tests, creating an Infected character without Ashes enabled doesn't choke, but the Doom Shield tree is missing.
