Object created from pool() is empty but producing a summary()

[evielopoo]

This code has been running fine for months:

coxfit1 <- with(imp30_mids, coxph(Surv(recid, fail) ~ vet))
summary(coxfit1)
coxfit1_pool <- pool(coxfit1)

However, starting yesterday it was returning number of observations = total number of failures, not the total number of failures + censored events. Also, my object "coxfit1_pool" is of class mipa and produces an estimate, but when I use the command view(coxfit1_pool), RStudio returns "error: object not found". Any idea what is going on here? It doesn't seem to be an issue with the imputed dataset itself (if I extract m=1 imputed dataset, it returns the correct number of observations and has no missing values).
