问题： 大修后审稿人迟迟不回复

6月末投稿，9月17日收到修稿意见，两位审稿人一位建议小修后接收，另一位建议大修，10月16日上传了修稿和回复信，两个月过去了，昨天写了封催稿信，今天编辑回复说We have sent your manuscript to be re-assessed by the original reviewer(s). Unfortunately, they have not been able to return a re-review report. We have approached the handling editor to suggest an alternative course of action to provide a decision. Our sincerest apologies for this delay, please be assured that we will do everything we can to ensure a decision can be reached as soon as possible.简而言之就是之前的审稿人都没回应，想问下如果审稿人迟迟不回复，难不成就一直拖着？或者再找新的审稿人？
