Hi,
Whenever I make a change in my mod with signals (only when removing signals when adding everything works fine) or for example uninstalling YARM mod I get following errors.
Thanks for the great mod.

Error when importing a model after removing some (not used by processor) signals from my mod.

The mod Compakt circuits (1.1.6) caused a non-recoverable error.
Please report this error to the mod author.

The mod Filter Combinator (1.0.6) caused a non-recoverable error.

I replaced filter combinator with my own processor and none of above errors appear anymore in case of uninstalling mods or making modifications in other mods.

There were known issues with that implementation of filter comb. The mod author states it's fixed, but there might be different issues. (Pls report there if so.)

You can always use the processor models from this thread, they are extremely optimized in terms of UPS & values range.
