I've just updated the mod with completely refactored core logic, so I wouldn't be surprised if I've introduced a bug or two on SOMEbody's machine.

Please give me the exact error message (a screenshot preferably) or, if it didn't crash, tell me exactly what you're doing and in which speed mode you're in (slow "-", fast "+", or accel "<"), what you expected to happen, and what happened instead.

Setting "Initial speed factor" to 0.5 locks you i place. 1 and 0.75 works, 0.5 does not. 0.33 crashed the game

778.731 Error MainLoop.cpp:1510: Exception at tick 229865998: The mod Progressive Running 2.0 (2.0.2) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event Progressive_Running_2_0::on_tick (ID 0)
Given value has to be larger than or equal to: -1
stack traceback:
[C]: in function 'newindex'

I was standing on some 350% speed concrete from pyanodons mod. (and had just updated from the 1.1 prefork version of this mod)
edit: "-" mode makes the locked state happen

Very high speed concrete breaks the slowing effect? Weird! I'll take a look, see what I can do. How many exoskeletons did you have, and do you have any other run speed bonuses applied from any other mod?

In the meantime if you still want to use the mod you can fetch the previous version's zip from the downloads tab and stick it in your mods folder. Just make sure to delete the newer zip file. (You can do this with any mod)

Only power armor, no exoskeletons. Don't think i have other mods adding speed, gui does not show any.
Save file if you need it: https://files.dbq.no/PyAE-nr1-2.0.zip (might miss 2-3 mods when syncing, they have been bugfixed/2.0ported by me locally)

Alright thanks. I've been coding all day so I'm not gonna try right now but I'll take a look tomorrow.
