Synapse4 keymap overwriting issue on Tautarus Pro

I’ve already sent this to support but I thought I’ll put this here too.

This is an issue I have only on Synapse4.

Basically, when ever I cycle keymap(I use 1 as main and 2 for some obscure shortcuts) and use it, Synapse can randomly overwrite the 2nd keymap with the mapping of 1st’s.

Here’s a video of me reproducing this issue by spamming keys while cycling, but this has happened multiple times when I’m using Tautarus normally and I don’t spam keys.


My temporary solution for this is to dupe the preset so I can switch to it when it happens, delete the original and dupe the dupe for next time...

    Commenting because I have the same problem and it’s a big issue for me mid-game when I suddenly find out I no longer have access to any of my abilities mid-fight. From your video it seems that it’s caused by just swapping keymaps too often or fast. You said that you’ve triggered this without spamming before. Have you noticed what the trigger is when you’re not spamming the switch keymap key?

    Coincidentally I’m currently using the same workaround, but mid fight it takes out way too much time and I’m usually dead by the time I’ve swapped to my backup profile. I love the compact format of the Tartarus Pro but if I can’t get this fixed I might have to shelve it.
