Strange warning message when linking events

[Djoustaine]

Hey everyone,

I'm encountering a warning message when using the link_events() function:

Warning message:
Unknown or uninitialised column: `replace`. 

It also pops up sometimes at different steps of setting up the goldfish objects, but it's hard to trace a systematic pattern. I can't easily share the data I'm using, but here is some information on the format of the datasets I'm using. Since I had compatibility issues with tibbles in the past, I first tried to transform the node set into a simple data frame, but nothing changes whether I do that correction or not.

I also include the packages that I've loaded for this session:

library(tidyverse)
library(here)
library(countrycode)
library(goldfish)

If anyone has run into something similar or has insights as to what might be triggering this warning, I’d appreciate it. Thanks in advance!
