Time domain&stacking of "time.slw" ?

[M1sh2]

Description:
In version 1.0.3715, smoking 4 swampweed in a row causes the game world speed to decrease to an unplayable level. The effect seems to stack indefinitely or incorrectly, making the game look like it has frozen or is running at 0.01x speed.
Environment:

OpenGothic Version: 1.0.3715
OS: Windows 11
GPU: NVIDIA GTX 1660 SUPER

Steps to Reproduce:

Start the game (OpenGothic 1.0.3715).
Obtain at least 4 swampweed
Use (smoke) them one after another in quick succession.
Observe the game world speed after the 4th joint.

Expected behavior:
The "slow-motion" effect should either have a cap, a fixed duration, or not stack to the point of a total standstill.
Actual behavior:
The game slows down completely. The only way to restore normal speed is by using an external Speedhack (e.g., via Cheat Engine) to force the game clock forward.
Additional context:
It seems the time dilation multiplier is being multiplied/added incorrectly when multiple items are used, leading to an effective speed of nearly zero.

Here, the fourth one stopped the game, and the effect hasn't worn off:

Hi, and thanks for report!
While there is an issue, that stacking is not implemented quite correct (and can yield into zero delta time) - I've changed it for now.

For longer term: timescale is pretty tricky. For example effect duration is measured in "time", white effect itself slows(or speeds up) time. Ideally, need to do some non trivial testing, to check what vanilla is doing - will leave it for other time.
