Combat buttons not showing up properly

[LittlePox]

Load this progress file and embark your travel; randomly walk until you start a fight. You'll notice you can't eat cured meat although there are plenty of them; you can't use the shield button either. Sometimes you can't even punch; that's the only way you can do damage. save.txt

When I base64-decode the save file, I see the following:

"cooldown": {
    "eat": -558.5,
    "shld": -550.5,
    "leaveBtn": -555.5
},

Looks like the same bug that I am having: I am unable to use meds or eat meat in combat. Save file here; when I decode my save file, I get the following:

"cooldown": {
    "attack_iron-sword": -0.5,
    "attack_steel-sword": -0.5,
    "eat": -261.5,
    "meds": -242,
    "continue": -663.5,
    "loot_takeEverything": -442,
    "gatherButton": 53.5,
    "trapsButton": 85.5
},

Apparently something has gone wrong with the cooldowns. I could cheat by removing the broken cooldowns and re-encoding the JSON document back into base64; but it's likely that the error could occur again in the future.

• Follow-up: I have removed the negative cooldowns from the save and reloaded it, which fixed the error.

Is there any specific way to replicate this issue? Providing more info may help people fix this.
