I just downloaded the games Weini 0.0.20 played in the CCRL 40/4. This is the game it has lost in the least number of moves:
https://lichess.org/aoEmr338
It looks like a 3-fold repetition bug where it just throws away its queen and therefore loses the match.
Sander is quite right. You have at least a serious repetition bug!
I downloaded the commented CCRL 40/40 for Weini 0.023 and cleaned it with a script,
thus Toms GameAnalyser can read it (filtered out won games before with Scid because
we are not interested in those)
Fiddled a bit with some settings in TGA and found at least 3 games already in a few minutes,
which have the same symptom.
When a rep is on the horizon even when eval is worse it suddenly starts to blunder a piece
or worsens its position instead of trying to force a repetition and take the draw. (or even 50 moves draw)
Here are two examples from the first sample (Weini White).
Example1:
Asymptotes eval also is wrong for a long while and Weini showing around -0.84 has a comfortable
positionally draw and could have just sat with its K around the Black passer on e3 awaiting a 3 time rep
or a 50 moves draw as Black can do nothing.
Instead it suddenly created a decisive weakness with 119.g6??
I could understand it if would show a positive score and attempts to win.

Example 2:
In this game it is even more visible. There was already a two time repetition after 57...Qf5, but suddenly
it played Nxb4?? with a slightly positive score though for only one ply (before always slightly negative).
