    • In one aspect, a method includes while a first content-presentation device is performing a content-replacement operation in which the first content-presentation device outputs a replacement advertisement segment in place of an advertisement segment, determining, by a computing system, that the advertisement segment is not an expected modifiable advertisement segment. The method also includes in response to determining that the advertisement segment is not the expected modifiable advertisement segment, determining, by the computing system, that the advertisement segment is ineligible for replacement. The method also includes in response to determining that the advertisement segment is ineligible for replacement, causing, by the computing system, at least one content-presentation device to perform, at a subsequent content-replacement opportunity, a corrective content-replacement operation in which the at least one content-presentation device outputs the advertisement segment in place of a subsequent modifiable advertisement segment that the at least one content-presentation device is scheduled to receive.

    • In one aspect, an example method includes (i) receiving, by a computing system, from a content-presentation device a request for supplemental content for a content-replacement operation, with the request including an identifier of a stored replacement advertisement segment; (ii) selecting, by the computing system, a replacement advertisement segment for output by the content-presentation device in place of a modifiable advertisement segment; (iii) determining, by the computing system, that the selected replacement advertisement segment is different from the stored replacement advertisement segment; (iv) determining, by the computing system, whether the stored replacement advertisement segment is a valid replacement for the content-replacement operation; (v) determining, by the computing system, that the content-presentation device should output the selected replacement advertisement segment instead of outputting the stored replacement advertisement segment; and (vi) causing, by the computing system, the selected replacement advertisement segment to be transmitted to the content-presentation device.
